-Thank you for taking the time to report this issue.
-
-To help us investigate and resolve this, we need more information. Please provide the following:
-
-> [!TIP]
-> Most issues turn out to be configuration errors rather than bugs. We encourage you to discuss your problem in our [Discord community](https://discord.gg/c84AZQhmpx) **before** opening an issue. The community can often help identify misconfigurations quickly, saving everyone time.
-
-## Required Information
-
-### Environment Details
-
- **Headscale version**: (run `headscale version`)
- **Tailscale client version**: (run `tailscale version`)
- **Operating System**: (e.g., Ubuntu 24.04, macOS 14, Windows 11)
- **Deployment method**: (binary, Docker, Kubernetes, etc.)
- **Reverse proxy**: (if applicable: nginx, Traefik, Caddy, etc. - include configuration)
-
-### Debug Information
-
-Please follow our [Debugging and Troubleshooting Guide](https://headscale.net/stable/ref/debug/) and provide:
-
-1. **Client netmap dump** (from affected Tailscale client):
-
-   ```bash
-   tailscale debug netmap > netmap.json
-   ```
-
-2. **Client status dump** (from affected Tailscale client):
-
-   ```bash
-   tailscale status --json > status.json
-   ```
-
-3. **Tailscale client logs** (if experiencing client issues):
-
-   ```bash
-   tailscale debug daemon-logs
-   ```
-
-   > [!IMPORTANT]
-   > We need logs from **multiple nodes** to understand the full picture:
-   >
-   > - The node(s) initiating connections
-   > - The node(s) being connected to
-   >
-   > Without logs from both sides, we cannot diagnose connectivity issues.
-
-4. **Headscale server logs** with `log.level: trace` enabled
-
-5. **Headscale configuration** (with sensitive values redacted - see rules below)
-
-6. **ACL/Policy configuration** (if using ACLs)
-
-7. **Proxy/Docker configuration** (if applicable - nginx.conf, docker-compose.yml, Traefik config, etc.)
-
-## Formatting Requirements
-
- **Attach long files** - Do not paste large logs or configurations inline. Use GitHub file attachments or GitHub Gists.
- **Use proper Markdown** - Format code blocks, logs, and configurations with appropriate syntax highlighting.
- **Structure your response** - Use the headings above to organize your information clearly.
-
-## Redaction Rules
-
-> [!CAUTION]
-> **Replace, do not remove.** Removing information makes debugging impossible.
-
-When redacting sensitive information:
-
- ✅ **Replace consistently** - If you change `alice@company.com` to `user1@example.com`, use `user1@example.com` everywhere (logs, config, policy, etc.)
- ✅ **Use meaningful placeholders** - `user1@example.com`, `bob@example.com`, `my-secret-key` are acceptable
- ❌ **Never remove information** - Gaps in data prevent us from correlating events across logs
- ❌ **Never redact IP addresses** - We need the actual IPs to trace network paths and identify issues
-
-**If redaction rules are not followed, we will be unable to debug the issue and will have to close it.**

-      Open source implementation of the Tailscale control server.
-      Headscale aims to implement a self-hosted, open source alternative to the
-      Tailscale control server. Headscale's goal is to provide self-hosters and
-      hobbyists with an open-source server they can use for their projects and
-      labs. It implements a narrow scope, a single Tailscale network (tailnet),
-      suitable for a personal use, or a small open-source organisation.

-# AGENTS.md
-
-Behavioural guidance for AI agents working in this repository. Reference
-material for complex procedures lives next to the code — integration
-testing is documented in [`cmd/hi/README.md`](cmd/hi/README.md) and
-[`integration/README.md`](integration/README.md). Read those files
-before running tests or writing new ones.
-
-Headscale is an open-source implementation of the Tailscale control server
-written in Go. It manages node registration, IP allocation, policy
-enforcement, and DERP routing for self-hosted tailnets.
-
-## Interaction Rules
-
-These rules govern how you work in this repo. They are listed first
-because they shape every other decision.
-
-### Ask with comprehensive multiple-choice options
-
-When you need to clarify intent, scope, or approach, use the
-`AskUserQuestion` tool (or a numbered list fallback) and present the user
-with a comprehensive set of options. Cover the likely branches explicitly
-and include an "other — please describe" escape.
-
- Bad: _"How should I handle expired nodes?"_
- Good: _"How should expired nodes be handled? (a) Remain visible to peers
-  but marked expired (current behaviour); (b) Hidden from peers entirely;
-  (c) Hidden from peers but visible in admin API; (d) Other."_
-
-This matters more than you think — open-ended questions waste a round
-trip and often produce a misaligned answer.
-
-### Read the documented procedure before running complex commands
-
-Before invoking any `hi` command, integration test, generator, or
-migration tool, read the referenced README in full —
-`cmd/hi/README.md` for running tests, `integration/README.md` for
-writing them. Never guess flags. If the procedure is not documented
-anywhere, ask the user rather than inventing one.
-
-### Map once, then act
-
-Use `Glob` / `Grep` to understand file structure, then execute. Do not
-re-explore the same area to "double-check" once you have a plan. Do not
-re-read files you edited in this session — the harness tracks state for
-you.
-
-### Fail fast, report up
-
-If a command fails twice with the same error, stop and report the exact
-error to the user with context. Do not loop through variants or
-"try one more thing". A repeated failure means your model of the problem
-is wrong.
-
-### Confirm scope for multi-file changes
-
-Before touching more than three files, show the user which files will
-change and why. Use plan mode (`ExitPlanMode`) for non-trivial work.
-
-### Prefer editing existing files
-
-Do not create new files unless strictly necessary. Do not generate helper
-abstractions, wrapper utilities, or "just in case" configuration. Three
-similar lines of code is better than a premature abstraction.
-
-## Quick Start
-
-```bash
-# Enter the nix dev shell (Go 1.26.1, buf, golangci-lint, prek)
-nix develop
-
-# Full development workflow: fmt + lint + test + build
-make dev
-
-# Individual targets
-make build           # build the headscale binary
-make test            # go test ./...
-make fmt             # format Go, docs, proto
-make lint            # lint Go, proto
-make generate        # regenerate protobuf code (after changes to proto/)
-make clean           # remove build artefacts
-
-# Direct go test invocations
-go test ./...
-go test -race ./...
-
-# Integration tests — read cmd/hi/README.md first
-go run ./cmd/hi doctor
-go run ./cmd/hi run "TestName"
-```
-
-Go 1.26.1 minimum (per `go.mod:3`). `nix develop` pins the exact toolchain
-used in CI.
-
-## Pre-Commit with prek
-
-`prek` installs git hooks that run the same checks as CI.
-
-```bash
-nix develop
-prek install            # one-time setup
-prek run                # run hooks on staged files
-prek run --all-files    # run hooks on the full tree
-```
-
-Hooks cover: file hygiene (trailing whitespace, line endings, BOM),
-syntax validation (JSON/YAML/TOML/XML), merge-conflict markers, private
-key detection, nixpkgs-fmt, prettier, and `golangci-lint` via
-`--new-from-rev=HEAD~1` (see `.pre-commit-config.yaml:59`). A manual
-invocation with an `upstream/main` remote is equivalent:
-
-```bash
-golangci-lint run --new-from-rev=upstream/main --timeout=5m --fix
-```
-
-`git commit --no-verify` is acceptable only for WIP commits on feature
-branches — never on `main`.

-  `poll.go`, `metrics.go`, `debug.go`, `tailsql.go`, `platform_config.go`
-  — top-level server files
- `state/` — central coordinator (`state.go`) and the copy-on-write
-  `NodeStore` (`node_store.go`). All cross-subsystem operations go
-  through `State`.
- `db/` — GORM layer, migrations, schema. `node.go`, `users.go`,
-  `api_key.go`, `preauth_keys.go`, `ip.go`, `policy.go`.
- `mapper/` — streaming batcher that distributes MapResponses to
-  clients: `batcher.go`, `node_conn.go`, `builder.go`, `mapper.go`.
-  Performance-critical.
- `policy/` — `policy/v2/` is **the** policy implementation. The
-  top-level `policy.go` is thin wrappers. There is no v1 directory.
- `routes/`, `dns/`, `derp/`, `types/`, `util/`, `templates/`, `capver/`
-  — routing, MagicDNS, relay, core types, helpers, client templates,
-  capability versioning.
- `servertest/` — in-memory test harness for server-level tests that
-  don't need Docker. Prefer this over `integration/` when possible.
- `assets/` — embedded UI assets.
-
-### `cmd/hi/` files
-
-`main.go`, `run.go`, `doctor.go`, `docker.go`, `cleanup.go`, `stats.go`,
-`README.md`. **Read `cmd/hi/README.md` before running any `hi` command.**
-
-## Architecture Essentials
-
- **`hscontrol/state/state.go`** is the central coordinator. Cross-cutting
-  operations (node updates, policy evaluation, IP allocation) go through
-  the `State` type, not directly to the database.
- **`NodeStore`** in `hscontrol/state/node_store.go` is a copy-on-write
-  in-memory cache backed by `atomic.Pointer[Snapshot]`. Every read is a
-  pointer load; writes rebuild a new snapshot and atomically swap. It is
-  the hot path for `MapRequest` processing and peer visibility.
- **The map-request sync point** is
-  `State.UpdateNodeFromMapRequest()` in
-  `hscontrol/state/state.go:2351`. This is where Hostinfo changes,
-  endpoint updates, and route advertisements land in the NodeStore.
- **Mapper subsystem** streams MapResponses via `batcher.go` and
-  `node_conn.go`. Changes here affect all connected clients.
- **Node registration flow**: noise handshake (`noise.go`) → auth
-  (`auth.go`) → state/DB persistence (`state/`, `db/`) → initial map
-  (`mapper/`).
-
-## Database Migration Rules
-
-These rules are load-bearing — violating them corrupts production
-databases. The `migrationsRequiringFKDisabled` map in
-`hscontrol/db/db.go:962` is frozen as of 2025-07-02 (see the comment at
-`db.go:989`). All new migrations must:
-
-1. **Never reorder existing migrations.** Migration order is immutable
-   once committed.
-2. **Only add new migrations to the end** of the migrations array.
-3. **Never disable foreign keys.** No new entries in
-   `migrationsRequiringFKDisabled`.
-4. **Use the migration ID format** `YYYYMMDDHHMM-short-description`
-   (timestamp + descriptive suffix). Example: `202602201200-clear-tagged-node-user-id`.
-5. **Never rename columns** that later migrations reference. Let
-   `AutoMigrate` create a new column if needed.
-
-## Tags-as-Identity
-
-Headscale enforces **tags XOR user ownership**: every node is either
-tagged (owned by tags) or user-owned (owned by a user namespace), never
-both. This is a load-bearing architectural invariant.
-
- **Use `node.IsTagged()`** (`hscontrol/types/node.go:221`) to determine
-  ownership, not `node.UserID().Valid()`. A tagged node may still have
-  `UserID` set for "created by" tracking — `IsTagged()` is authoritative.
- `IsUserOwned()` (`node.go:227`) returns `!IsTagged()`.
- Tagged nodes are presented to Tailscale as the special
-  `TaggedDevices` user (`hscontrol/types/users.go`, ID `2147455555`).
- `SetTags` validation is enforced by `validateNodeOwnership()` in
-  `hscontrol/state/tags.go`.
- Examples and edge cases live in `hscontrol/types/node_tags_test.go`
-  and `hscontrol/grpcv1_test.go` (`TestSetTags_*`).
-
-**Don't do this**:
-
-```go
-if node.UserID().Valid() { /* assume user-owned */ }       // WRONG
-if node.UserID().Valid() && !node.IsTagged() { /* ok */ }  // correct
-```
-
-## Policy Engine
-
-`hscontrol/policy/v2/policy.go` is the policy implementation. The
-top-level `hscontrol/policy/policy.go` contains only wrapper functions
-around v2. There is no v1 directory.
-
-Key concepts an agent will encounter:
-
- **Autogroups**: `autogroup:self`, `autogroup:member`, `autogroup:internet`
- **Tag owners**: IP-based authorization for who can claim a tag
- **Route approvals**: auto-approval of subnet routes by policy
- **SSH policies**: SSH access control via grants
- **HuJSON** parsing for policy files
-
-For usage examples, read `hscontrol/policy/v2/policy_test.go`. For ACL
-reference documentation, see `docs/`.
-
-## Integration Testing
-
-**Before running any `hi` command, read `cmd/hi/README.md` in full.**
-Guessing at `hi` flags leads to broken runs and stale containers.
-
-Test-authoring patterns (`EventuallyWithT`, `IntegrationSkip`, helper
-variants, scenario setup) are documented in `integration/README.md`.
-
-Key reminders:
-
- Integration test functions **must** start with `IntegrationSkip(t)`.
- External calls (`client.Status`, `headscale.ListNodes`, etc.) belong
-  inside `EventuallyWithT`; state-mutating commands (`tailscale set`)
-  must not.
- Tests generate ~100 MB of logs per run under `control_logs/{runID}/`.
-  Prune old runs if disk is tight.
- Flakes are almost always code, not infrastructure. Read `hs-*.stderr.log`
-  before blaming Docker.
-
-## Code Conventions
-
- **Commit messages** follow Go-style `package: imperative description`.
-  Recent examples from `git log`:
-  - `db: scope DestroyUser to only delete the target user's pre-auth keys`
-  - `state: fix policy change race in UpdateNodeFromMapRequest`
-  - `integration: fix ACL tests for address-family-specific resolve`
-
-  Not Conventional Commits. No `feat:`/`chore:`/`docs:` prefixes.
-
- **Protobuf regeneration**: changes under `proto/` require
-  `make generate` (which runs `buf generate`) and should land in a
-  **separate commit** from the callers that use the regenerated types.
- **Formatting** is enforced by `golangci-lint` with `golines` (width 88)
-  and `gofumpt`. Run `make fmt` or rely on the pre-commit hook.
- **Logging** uses `zerolog`. Prefer single-line chains
-  (`log.Info().Str(...).Msg(...)`). For 4+ fields or conditional fields,
-  build incrementally and **reassign** the event variable:
-  `e = e.Str("k", v)`. Forgetting to reassign silently drops the field.
- **Tests**: prefer `hscontrol/servertest/` for server-level tests that
-  don't need Docker — faster than full integration tests.
-
-## Gotchas
-
- **Database**: SQLite for local dev, PostgreSQL for integration-heavy
-  tests (`go run ./cmd/hi run "..." --postgres`). Some race conditions
-  only surface on one backend.
- **NodeStore writes** rebuild a full snapshot. Measure before changing
-  hot-path code.
- **`.claude/agents/` is deprecated.** Do not create new agent files
-  there. Put behavioural guidance in this file and procedural guidance
-  in the nearest README.
- **Do not edit `gen/`** — it is regenerated from `proto/` by
-  `make generate`.
- **Proto changes + code changes should be two commits**, not one.

-# hi — Headscale Integration test runner
-
-`hi` wraps Docker container orchestration around the tests in
-[`../../integration`](../../integration) and extracts debugging artefacts
-(logs, database snapshots, MapResponse protocol captures) for post-mortem
-analysis.
-
-**Read this file in full before running any `hi` command.** The test
-runner has sharp edges — wrong flags produce stale containers, lost
-artefacts, or hung CI.
-
-For test-authoring patterns (scenario setup, `EventuallyWithT`,
-`IntegrationSkip`, helper variants), read
-[`../../integration/README.md`](../../integration/README.md).
-
-## Quick Start
-
-```bash
-# Verify system requirements (Docker, Go, disk space, images)
-go run ./cmd/hi doctor
-
-# Run a single test (the default flags are tuned for development)
-go run ./cmd/hi run "TestPingAllByIP"
-
-# Run a database-heavy test against PostgreSQL
-go run ./cmd/hi run "TestExpireNode" --postgres
-
-# Pattern matching
-go run ./cmd/hi run "TestSubnet*"
-```
-
-Run `doctor` before the first `run` in any new environment. Tests
-generate ~100 MB of logs per run in `control_logs/`; `doctor` verifies
-there is enough space and that the required Docker images are available.
-

-| `--clean-after`     | `true`         | Clean this run's containers after completion                                |
-| `--keep-on-failure` | `false`        | Preserve containers for manual inspection on failure                        |
-| `--logs-dir`        | `control_logs` | Where to save run artefacts                                                 |
-| `--verbose`         | `false`        | Verbose output                                                              |
-| `--stats`           | `false`        | Collect container resource-usage stats                                      |
-| `--hs-memory-limit` | `0`            | Fail if any headscale container exceeds N MB (0 = disabled)                 |
-| `--ts-memory-limit` | `0`            | Fail if any tailscale container exceeds N MB                                |
-
-### Timeout guidance
-
-The default `120m` is generous for a single test. If you must tune it,
-these are realistic floors by category:
-
-| Test type                 | Minimum     | Examples                              |
-| ------------------------- | ----------- | ------------------------------------- |
-| Basic functionality / CLI | 900s (15m)  | `TestPingAllByIP`, `TestCLI*`         |
-| Route / ACL               | 1200s (20m) | `TestSubnet*`, `TestACL*`             |
-| HA / failover             | 1800s (30m) | `TestHASubnetRouter*`                 |
-| Long-running              | 2100s (35m) | `TestNodeOnlineStatus` (~12 min body) |
-| Full suite                | 45m         | `go test ./integration -timeout 45m`  |
-
-**Never** use the shell `timeout` command around `hi`. It kills the
-process mid-cleanup and leaves stale containers:
-
-```bash
-timeout 300 go run ./cmd/hi run "TestName"   # WRONG — orphaned containers
-go run ./cmd/hi run "TestName" --timeout=900s  # correct
-```
-
-## Concurrent Execution
-
-Multiple `hi run` invocations can run simultaneously on the same Docker
-daemon. Each invocation gets a unique **Run ID** (format
-`YYYYMMDD-HHMMSS-6charhash`, e.g. `20260409-104215-mdjtzx`).
-
- **Container names** include the short run ID: `ts-mdjtzx-1-74-fgdyls`
- **Docker labels**: `hi.run-id={runID}` on every container
- **Port allocation**: dynamic — kernel assigns free ports, no conflicts
- **Cleanup isolation**: each run cleans only its own containers
- **Log directories**: `control_logs/{runID}/`
-
-```bash
-# Start three tests in parallel — each gets its own run ID
-go run ./cmd/hi run "TestPingAllByIP" &
-go run ./cmd/hi run "TestACLAllowUserDst" &
-go run ./cmd/hi run "TestOIDCAuthenticationPingAll" &
-```
-
-### Safety rules for concurrent runs
-
- ✅ Your run cleans only containers labelled with its own `hi.run-id`
- ✅ `--clean-before` removes only stopped/exited containers
- ❌ **Never** run `docker rm -f $(docker ps -q --filter name=hs-)` —
-  this destroys other agents' live test sessions
- ❌ **Never** run `docker system prune -f` while any tests are running
- ❌ **Never** run `hi clean containers` / `hi clean all` while other
-  tests are running — both kill all test containers on the daemon
-
-To identify your own containers:
-
-```bash
-docker ps --filter "label=hi.run-id=20260409-104215-mdjtzx"
-```
-
-The run ID appears at the top of the `hi run` output — copy it from
-there rather than trying to reconstruct it.
-
-## Artefacts
-
-Every run saves debugging artefacts under `control_logs/{runID}/`:
-
-```
-control_logs/20260409-104215-mdjtzx/
-├── hs-<test>-<hash>.stderr.log        # headscale server errors
-├── hs-<test>-<hash>.stdout.log        # headscale server output
-├── hs-<test>-<hash>.db                # database snapshot (SQLite)
-├── hs-<test>-<hash>_metrics.txt       # Prometheus metrics dump
-├── hs-<test>-<hash>-mapresponses/     # MapResponse protocol captures
-├── ts-<client>-<hash>.stderr.log      # tailscale client errors
-├── ts-<client>-<hash>.stdout.log      # tailscale client output
-└── ts-<client>-<hash>_status.json     # client network-status dump
-```
-
-Artefacts persist after cleanup. Old runs accumulate fast — delete
-unwanted directories to reclaim disk.
-
-## Debugging workflow
-
-When a test fails, read the artefacts **in this order**:
-
-1. **`hs-*.stderr.log`** — headscale server errors, panics, policy
-   evaluation failures. Most issues originate server-side.
-
-   ```bash
-   grep -E "ERROR|panic|FATAL" control_logs/*/hs-*.stderr.log
-   ```
-
-2. **`ts-*.stderr.log`** — authentication failures, connectivity issues,
-   DNS resolution problems on the client side.
-
-3. **MapResponse JSON** in `hs-*-mapresponses/` — protocol-level
-   debugging for network map generation, peer visibility, route
-   distribution, policy evaluation results.
-
-   ```bash
-   ls control_logs/*/hs-*-mapresponses/
-   jq '.Peers[] | {Name, Tags, PrimaryRoutes}' \
-       control_logs/*/hs-*-mapresponses/001.json
-   ```
-
-4. **`*_status.json`** — client peer-connectivity state.
-
-5. **`hs-*.db`** — SQLite snapshot for post-mortem consistency checks.
-
-   ```bash
-   sqlite3 control_logs/<runID>/hs-*.db
-   sqlite> .tables
-   sqlite> .schema nodes
-   sqlite> SELECT id, hostname, user_id, tags FROM nodes WHERE hostname LIKE '%problematic%';
-   ```
-
-6. **`*_metrics.txt`** — Prometheus dumps for latency, NodeStore
-   operation timing, database query performance, memory usage.
-
-## Heuristic: infrastructure vs code
-
-**Before blaming Docker, disk, or network: read `hs-*.stderr.log` in
-full.** In practice, well over 99% of failures are code bugs (policy
-evaluation, NodeStore sync, route approval) rather than infrastructure.
-
-Actual infrastructure failures have signature error messages:
-
-| Signature                                                       | Cause                     | Fix                                                           |
-| --------------------------------------------------------------- | ------------------------- | ------------------------------------------------------------- |
-| `failed to resolve "hs-...": no DNS fallback candidates remain` | Docker DNS                | Reset Docker networking                                       |
-| `container creation timeout`, no progress >2 min                | Resource exhaustion       | `docker system prune -f` (when no other tests running), retry |
-| OOM kills, slow Docker daemon                                   | Too many concurrent tests | Reduce concurrency, wait for completion                       |
-| `no space left on device`                                       | Disk full                 | Delete old `control_logs/`                                    |
-
-If you don't see a signature error, **assume it's a code regression** —
-do not retry hoping the flake goes away.
-
-## Common failure patterns (code bugs)
-
-### Route advertisement timing
-
-Test asserts route state before the client has finished propagating its
-Hostinfo update. Symptom: `nodes[0].GetAvailableRoutes()` empty when
-the test expects a route.
-
- **Wrong fix**: `time.Sleep(5 * time.Second)` — fragile and slow.
- **Right fix**: wrap the assertion in `EventuallyWithT`. See
-  [`../../integration/README.md`](../../integration/README.md).
-
-### NodeStore sync issues
-
-Route changes not reflected in the NodeStore snapshot. Symptom: route
-advertisements in logs but no tracking updates in subsequent reads.
-
-The sync point is `State.UpdateNodeFromMapRequest()` in
-`hscontrol/state/state.go`. If you added a new kind of client state
-update, make sure it lands here.
-
-### HA failover: routes disappearing on disconnect
-
-`TestHASubnetRouterFailover` fails because approved routes vanish when
-a subnet router goes offline. **This is a bug, not expected behaviour.**
-Route approval must not be coupled to client connectivity — routes
-stay approved; only the primary-route selection is affected by
-connectivity.
-
-### Policy evaluation race
-
-Symptom: tests that change policy and immediately assert peer visibility
-fail intermittently. Policy changes trigger async recomputation.
-
- See recent fixes in `git log -- hscontrol/state/` for examples (e.g.
-  the `PolicyChange` trigger on every Connect/Disconnect).
-
-### SQLite vs PostgreSQL timing differences
-
-Some race conditions only surface on one backend. If a test is flaky,
-try the other backend with `--postgres`:
-
-```bash
-go run ./cmd/hi run "TestName" --postgres --verbose
-```
-
-PostgreSQL generally has more consistent timing; SQLite can expose
-races during rapid writes.
-
-## Keeping containers for inspection
-
-If you need to inspect a failed test's state manually:
-
-```bash
-go run ./cmd/hi run "TestName" --keep-on-failure
-# containers survive — inspect them
-docker exec -it ts-<runID>-<...> /bin/sh
-docker logs hs-<runID>-<...>
-# clean up manually when done
-go run ./cmd/hi clean all   # only when no other tests are running
-```

-## What is the recommended update path? Can I skip multiple versions while updating?
-
-Please follow the steps outlined in the [upgrade guide](../setup/upgrade.md) to update your existing Headscale
-installation. Its required to update from one stable version to the next (e.g. 0.26.0 → 0.27.1 → 0.28.0) without
-skipping minor versions in between. You should always pick the latest available patch release.
-
-Be sure to check the [changelog](https://github.com/juanfont/headscale/blob/main/CHANGELOG.md) for version specific
-upgrade instructions and breaking changes.
-
-## Scaling / How many clients does Headscale support?
-
-It depends. As often stated, Headscale is not enterprise software and our focus
-is homelabbers and self-hosters. Of course, we do not prevent people from using
-it in a commercial/professional setting and often get questions about scaling.
-
-Please note that when Headscale is developed, performance is not part of the
-consideration as the main audience is considered to be users with a modest
-amount of devices. We focus on correctness and feature parity with Tailscale
-SaaS over time.
-
-To understand if you might be able to use Headscale for your use case, I will
-describe two scenarios in an effort to explain what is the central bottleneck
-of Headscale:
-
-1. An environment with 1000 servers
-
-    - they rarely "move" (change their endpoints)
-    - new nodes are added rarely
-
-1. An environment with 80 laptops/phones (end user devices)
-
-    - nodes move often, e.g. switching from home to office
-
-Headscale calculates a map of all nodes that need to talk to each other,
-creating this "world map" requires a lot of CPU time. When an event that
-requires changes to this map happens, the whole "world" is recalculated, and a
-new "world map" is created for every node in the network.
-
-This means that under certain conditions, Headscale can likely handle 100s
-of devices (maybe more), if there is _little to no change_ happening in the
-network. For example, in Scenario 1, the process of computing the world map is
-extremely demanding due to the size of the network, but when the map has been
-created and the nodes are not changing, the Headscale instance will likely
-return to a very low resource usage until the next time there is an event
-requiring the new map.
-
-In the case of Scenario 2, the process of computing the world map is less
-demanding due to the smaller size of the network, however, the type of nodes
-will likely change frequently, which would lead to a constant resource usage.
-
-Headscale will start to struggle when the two scenarios overlap, e.g. many nodes
-with frequent changes will cause the resource usage to remain constantly high.
-In the worst case scenario, the queue of nodes waiting for their map will grow
-to a point where Headscale never will be able to catch up, and nodes will never
-learn about the current state of the world.
-
-We expect that the performance will improve over time as we improve the code
-base, but it is not a focus. In general, we will never make the tradeoff to make
-things faster on the cost of less maintainable or readable code. We are a small
-team and have to optimise for maintainability.
-
 ## Which database should I use?

 We recommend the use of SQLite as database for headscale:

 - SQLite is simple to setup and easy to use
- It scales well for all of headscale's use cases
+- It scales well for all of headscale's usecases
 - Development and testing happens primarily on SQLite
 - PostgreSQL is still supported, but is considered to be in "maintenance mode"

 The headscale project itself does not provide a tool to migrate from PostgreSQL to SQLite. Please have a look at [the
 related tools documentation](../ref/integration/tools.md) for migration tooling provided by the community.

-The choice of database has little to no impact on the performance of the server,
-see [Scaling / How many clients does Headscale support?](#scaling-how-many-clients-does-headscale-support) for understanding how Headscale spends its resources.

 ## Can I use headscale and tailscale on the same machine?

 Running headscale on a machine that is also in the tailnet can cause problems with subnet routers, traffic relay nodes, and MagicDNS. It might work, but it is not supported.
-
-## Why do two nodes see each other in their status, even if an ACL allows traffic only in one direction?
-
-A frequent use case is to allow traffic only from one node to another, but not the other way around. For example, the
-workstation of an administrator should be able to connect to all nodes but the nodes themselves shouldn't be able to
-connect back to the administrator's node. Why do all nodes see the administrator's workstation in the output of
-`tailscale status`?
-
-This is essentially how Tailscale works. If traffic is allowed to flow in one direction, then both nodes see each other
-in their output of `tailscale status`. Traffic is still filtered according to the ACL, with the exception of
-`tailscale ping` which is always allowed in either direction.
-
-See also <https://tailscale.com/kb/1087/device-visibility>.
-
-## My policy is stored in the database and Headscale refuses to start due to an invalid policy. How can I recover?
-
-Headscale checks if the policy is valid during startup and refuses to start if it detects an error. The error message
-indicates which part of the policy is invalid. Follow these steps to fix your policy:
-
- Dump the policy to a file: `headscale policy get --bypass-grpc-and-access-database-directly > policy.json`
- Edit and fixup `policy.json`. Use the command `headscale policy check --file policy.json` to validate the policy.
- Load the modified policy: `headscale policy set --bypass-grpc-and-access-database-directly --file policy.json`
- Start Headscale as usual.
-
-!!! warning "Full server configuration required"
-
-    The above commands to get/set the policy require a complete server configuration file including database settings. A
-    minimal config to [control Headscale via remote CLI](../ref/api.md#grpc) is not sufficient. You may use
-    `headscale -c /path/to/config.yaml` to specify the path to an alternative configuration file.
-
-## How can I migrate back to the recommended IP prefixes?
-
-Tailscale only supports the IP prefixes `100.64.0.0/10` and `fd7a:115c:a1e0::/48` or smaller subnets thereof. The
-following steps can be used to migrate from unsupported IP prefixes back to the supported and recommended ones.
-
-!!! warning "Backup and test in a demo environment required"
-
-    The commands below update the IP addresses of all nodes in your tailnet and this might have a severe impact in your
-    specific environment. At a minimum:
-
-    - [Create a backup of your database](../setup/upgrade.md#backup)
-    - Test the commands below in a representive demo environment. This allows to catch subsequent connectivity errors
-      early and see how the tailnet behaves in your specific environment.
-
- Stop Headscale
- Restore the default prefixes in the [configuration file](../ref/configuration.md):
-    ```yaml
-    prefixes:
-      v4: 100.64.0.0/10
-      v6: fd7a:115c:a1e0::/48
-    ```
- Update the `nodes.ipv4` and `nodes.ipv6` columns in the database and assign each node a unique IPv4 and IPv6 address.
-  The following SQL statement assigns IP addresses based on the node ID:
-    ```sql
-    UPDATE nodes
-    SET ipv4=concat('100.64.', id/256, '.', id%256),
-        ipv6=concat('fd7a:115c:a1e0::', format('%x', id));
-    ```
- Update the [policy](../ref/acls.md) to reflect the IP address changes (if any)
- Start Headscale
-
-Nodes should reconnect within a few seconds and pickup their newly assigned IP addresses.
-
-## How can I avoid to send logs to Tailscale Inc?
-
-A Tailscale client [collects logs about its operation and connection attempts with other
-clients](https://tailscale.com/kb/1011/log-mesh-traffic#client-logs) and sends them to a central log service operated by
-Tailscale Inc.
-
-Headscale, by default, instructs clients to disable log submission to the central log service. This configuration is
-applied by a client once it successfully connected with Headscale. See the configuration option `logtail.enabled` in the
-[configuration file](../ref/configuration.md) for details.
-
-Alternatively, logging can also be disabled on the client side. This is independent of Headscale and opting out of
-client logging disables log submission early during client startup. The configuration is operating system specific and
-is usually achieved by setting the environment variable `TS_NO_LOGS_NO_SUPPORT=true` or by passing the flag
-`--no-logs-no-support` to `tailscaled`. See
-<https://tailscale.com/kb/1011/log-mesh-traffic#opting-out-of-client-logging> for details.

-To enable and configure ACLs in Headscale, you need to specify the path to your ACL policy file in the `policy.path` key in `config.yaml`.

-## Simple Examples
-
- [**Allow All**](https://tailscale.com/kb/1192/acl-samples#allow-all-default-acl): If you define an ACL file but completely omit the `"acls"` field from its content, Headscale will default to an "allow all" policy.

- [**Deny All**](https://tailscale.com/kb/1192/acl-samples#deny-all): To prevent all communication within your tailnet, you can include an empty array for the `"acls"` field in your policy file.

-## Autogroups
-
-Headscale supports several autogroups that automatically include users, destinations, or devices with specific properties. Autogroups provide a convenient way to write ACL rules without manually listing individual users or devices.
-
-### `autogroup:internet`
-
-Allows access to the internet through [exit nodes](routes.md#exit-node). Can only be used in ACL destinations.
-
-```json
-{
-  "action": "accept",
-  "src": ["group:users"],
-  "dst": ["autogroup:internet:*"]

-```
-
-### `autogroup:member`

-Includes all [personal (untagged) devices](registration.md/#identity-model).

-```json
-{
-  "action": "accept",
-  "src": ["autogroup:member"],
-  "dst": ["tag:prod-app-servers:80,443"]

-
-### `autogroup:tagged`
-
-Includes all devices that [have at least one tag](registration.md/#identity-model).
-
-```json
-{
-  "action": "accept",
-  "src": ["autogroup:tagged"],
-  "dst": ["tag:monitoring:9090"]
-}
-```
-
-### `autogroup:self`
-
-!!! warning "The current implementation of `autogroup:self` is inefficient"
-
-Includes devices where the same user is authenticated on both the source and destination. Does not include tagged devices. Can only be used in ACL destinations.
-
-```json
-{
-  "action": "accept",
-  "src": ["autogroup:member"],
-  "dst": ["autogroup:self:*"]
-}
-```
-
-*Using `autogroup:self` may cause performance degradation on the Headscale coordinator server in large deployments, as filter rules must be compiled per-node rather than globally and the current implementation is not very efficient.*
-
-If you experience performance issues, consider using more specific ACL rules or limiting the use of `autogroup:self`.
-
-```json
-{
-  // The following rules allow internal users to communicate with their
-  // own nodes in case autogroup:self is causing performance issues.

-# API
-
-Headscale provides a [HTTP REST API](#rest-api) and a [gRPC interface](#grpc) which may be used to integrate a [web
-interface](integration/web-ui.md), [remote control Headscale](#setup-remote-control) or provide a base for custom
-integration and tooling.
-
-Both interfaces require a valid API key before use. To create an API key, log into your Headscale server and generate
-one with the default expiration of 90 days:
-
-```shell
-headscale apikeys create
-```
-
-Copy the output of the command and save it for later. Please note that you can not retrieve an API key again. If the API
-key is lost, expire the old one, and create a new one.
-
-To list the API keys currently associated with the server:
-
-```shell
-headscale apikeys list
-```
-
-and to expire an API key:
-
-```shell
-headscale apikeys expire --prefix <PREFIX>
-```
-
-## REST API
-
- API endpoint: `/api/v1`, e.g. `https://headscale.example.com/api/v1`
- Documentation: `/swagger`, e.g. `https://headscale.example.com/swagger`
- Headscale Version: `/version`, e.g. `https://headscale.example.com/version`
- Authenticate using HTTP Bearer authentication by sending the [API key](#api) with the HTTP `Authorization: Bearer <API_KEY>` header.
-
-Start by [creating an API key](#api) and test it with the examples below. Read the API documentation provided by your
-Headscale server at `/swagger` for details.
-
-=== "Get details for all users"
-
-    ```console
-    curl -H "Authorization: Bearer <API_KEY>" \
-        https://headscale.example.com/api/v1/user
-    ```
-
-=== "Get details for user 'bob'"
-
-    ```console
-    curl -H "Authorization: Bearer <API_KEY>" \
-        https://headscale.example.com/api/v1/user?name=bob
-    ```
-
-=== "Register a node"
-
-    ```console
-    curl -H "Authorization: Bearer <API_KEY>" \
-        --json '{"user": "<USER>", "authId": "AUTH_ID>"}' \
-        https://headscale.example.com/api/v1/auth/register
-    ```
-
-## gRPC
-
-The gRPC interface can be used to control a Headscale instance from a remote machine with the `headscale` binary.
-
-### Prerequisite
-
- A workstation to run `headscale` (any supported platform, e.g. Linux).
- A Headscale server with gRPC enabled.
- Connections to the gRPC port (default: `50443`) are allowed.
- Remote access requires an encrypted connection via TLS.
- An [API key](#api) to authenticate with the Headscale server.
-
-### Setup remote control
-
-1. Download the [`headscale` binary from GitHub's release page](https://github.com/juanfont/headscale/releases). Make
-   sure to use the same version as on the server.
-
-1. Put the binary somewhere in your `PATH`, e.g. `/usr/local/bin/headscale`
-
-1. Make `headscale` executable: `chmod +x /usr/local/bin/headscale`
-
-1. [Create an API key](#api) on the Headscale server.
-
-1. Provide the connection parameters for the remote Headscale server either via a minimal YAML configuration file or
-   via environment variables:
-
-    === "Minimal YAML configuration file"
-
-        ```yaml title="config.yaml"
-        cli:
-            address: <HEADSCALE_ADDRESS>:<PORT>
-            api_key: <API_KEY>
-        ```
-
-    === "Environment variables"
-
-        ```shell
-        export HEADSCALE_CLI_ADDRESS="<HEADSCALE_ADDRESS>:<PORT>"
-        export HEADSCALE_CLI_API_KEY="<API_KEY>"
-        ```
-
-    This instructs the `headscale` binary to connect to a remote instance at `<HEADSCALE_ADDRESS>:<PORT>`, instead of
-    connecting to the local instance.
-
-1. Test the connection by listing all nodes:
-
-    ```shell
-    headscale nodes list
-    ```
-
-    You should now be able to see a list of your nodes from your workstation, and you can
-    now control the Headscale server from your workstation.
-
-### Behind a proxy
-
-It's possible to run the gRPC remote endpoint behind a reverse proxy, like Nginx, and have it run on the _same_ port as Headscale.
-
-While this is _not a supported_ feature, an example on how this can be set up on
-[NixOS is shown here](https://github.com/kradalby/dotfiles/blob/4489cdbb19cddfbfae82cd70448a38fde5a76711/machines/headscale.oracldn/headscale.nix#L61-L91).
-
-### Troubleshooting
-
- Make sure you have the _same_ Headscale version on your server and workstation.
- Ensure that connections to the gRPC port are allowed.
- Verify that your TLS certificate is valid and trusted.
- If you don't have access to a trusted certificate (e.g. from Let's Encrypt), either:
-    - Add your self-signed certificate to the trust store of your OS _or_
-    - Disable certificate verification by either setting `cli.insecure: true` in the configuration file or by setting
-      `HEADSCALE_CLI_INSECURE=1` via an environment variable. We do **not** recommend to disable certificate validation.

-The log levels `debug` and `trace` can be useful to get more information from Headscale.
-
-```yaml hl_lines="3"
-log:
-  # Valid log levels: panic, fatal, error, warn, info, debug, trace
-  level: debug
-```
-
-### Database logging
-
-The database debug mode logs all database queries. Enable it to see how Headscale interacts with its database. This also
-requires the application log level to be set to either `debug` or `trace`.
-
-```yaml hl_lines="3 7"
-database:
-  # Enable debug mode. This setting requires the log.level to be set to "debug" or "trace".
-  debug: false
-
-log:
-  # Valid log levels: panic, fatal, error, warn, info, debug, trace
-  level: debug
-```
-
-### Metrics and debug endpoint
-
-Headscale provides a metrics and debug endpoint. It allows to introspect different aspects such as:
-
- Information about the Go runtime, memory usage and statistics
- Connected nodes and pending registrations
- Active ACLs, filters and SSH policy
- Current DERPMap
- Prometheus metrics
-
-!!! warning "Keep the metrics and debug endpoint private"
-
-    The listen address and port can be configured with the `metrics_listen_addr` variable in the [configuration
-    file](./configuration.md). By default it listens on localhost, port 9090.
-
-    Keep the metrics and debug endpoint private to your internal network and don't expose it to the Internet.
-
-    The metrics and debug interface can be disabled completely by setting `metrics_listen_addr: null` in the
-    [configuration file](./configuration.md).
-
-Query metrics via <http://localhost:9090/metrics> and get an overview of available debug information via
-<http://localhost:9090/debug/>. Metrics may be queried from outside localhost but the debug interface is subject to
-additional protection despite listening on all interfaces.
-
-=== "Direct access"
-
-    Access the debug interface directly on the server where Headscale is installed.
-
-    ```console
-    curl http://localhost:9090/debug/
-    ```
-
-=== "SSH port forwarding"
-
-    Use SSH port forwarding to forward Headscale's metrics and debug port to your device.
-
-    ```console
-    ssh <HEADSCALE_SERVER> -L 9090:localhost:9090
-    ```
-
-    Access the debug interface on your device by opening <http://localhost:9090/debug/> in your web browser.
-
-=== "Via debug key"
-
-    The access control of the debug interface supports the use of a debug key. Traffic is accepted if the path to a
-    debug key is set via the environment variable `TS_DEBUG_KEY_PATH` and the debug key sent as value for `debugkey`
-    parameter with each request.
-
-    ```console
-    openssl rand -hex 32 | tee debugkey.txt
-    export TS_DEBUG_KEY_PATH=debugkey.txt
-    headscale serve
-    ```
-
-    Access the debug interface on your device by opening `http://<IP_OF_HEADSCALE>:9090/debug/?debugkey=<DEBUG_KEY>` in
-    your web browser. The `debugkey` parameter must be sent with every request.
-
-=== "Via debug IP address"
-
-    The debug endpoint expects traffic from localhost. A different debug IP address may be configured by setting the
-    `TS_ALLOW_DEBUG_IP` environment variable before starting Headscale. The debug IP address is ignored when the HTTP
-    header `X-Forwarded-For` is present.
-
-    ```console
-    export TS_ALLOW_DEBUG_IP=192.168.0.10       # IP address of your device
-    headscale serve
-    ```
-
-    Access the debug interface on your device by opening `http://<IP_OF_HEADSCALE>:9090/debug/` in your web browser.

-# DERP
-
-A [DERP (Designated Encrypted Relay for Packets) server](https://tailscale.com/kb/1232/derp-servers) is mainly used to
-relay traffic between two nodes in case a direct connection can't be established. Headscale provides an embedded DERP
-server to ensure seamless connectivity between nodes.
-
-## Configuration
-
-DERP related settings are configured within the `derp` section of the [configuration file](./configuration.md). The
-following sections only use a few of the available settings, check the [example configuration](./configuration.md) for
-all available configuration options.
-
-### Enable embedded DERP
-
-Headscale ships with an embedded DERP server which allows to run your own self-hosted DERP server easily. The embedded
-DERP server is disabled by default and needs to be enabled. In addition, you should configure the public IPv4 and public
-IPv6 address of your Headscale server for improved connection stability:
-
-```yaml title="config.yaml" hl_lines="3-5"
-derp:
-  server:
-    enabled: true
-    ipv4: 198.51.100.1
-    ipv6: 2001:db8::1
-```
-
-Keep in mind that [additional ports are needed to run a DERP server](../setup/requirements.md#ports-in-use). Besides
-relaying traffic, it also uses STUN (udp/3478) to help clients discover their public IP addresses and perform NAT
-traversal. [Check DERP server connectivity](#check-derp-server-connectivity) to see if everything works.
-
-### Remove Tailscale's DERP servers
-
-Once enabled, Headscale's embedded DERP is added to the list of free-to-use [DERP
-servers](https://tailscale.com/kb/1232/derp-servers) offered by Tailscale Inc. To only use Headscale's embedded DERP
-server, disable the loading of the default DERP map:
-
-```yaml title="config.yaml" hl_lines="6"
-derp:
-  server:
-    enabled: true
-    ipv4: 198.51.100.1
-    ipv6: 2001:db8::1
-  urls: []
-```
-
-!!! warning "Single point of failure"
-
-    Removing Tailscale's DERP servers means that there is now just a single DERP server available for clients. This is a
-    single point of failure and could hamper connectivity.
-
-    [Check DERP server connectivity](#check-derp-server-connectivity) with your embedded DERP server before removing
-    Tailscale's DERP servers.
-
-### Customize DERP map
-
-The DERP map offered to clients can be customized with a [dedicated YAML-configuration
-file](https://github.com/juanfont/headscale/blob/main/derp-example.yaml). This allows to modify previously loaded DERP
-maps fetched via URL or to offer your own, custom DERP servers to nodes.
-
-=== "Remove specific DERP regions"
-
-    The free-to-use [DERP servers](https://tailscale.com/kb/1232/derp-servers) are organized into regions via a region
-    ID. You can explicitly disable a specific region by setting its region ID to `null`. The following sample
-    `derp.yaml` disables the New York DERP region (which has the region ID 1):
-
-    ```yaml title="derp.yaml"
-    regions:
-      1: null
-    ```
-
-    Use the following configuration to serve the default DERP map (excluding New York) to nodes:
-
-    ```yaml title="config.yaml" hl_lines="6 7"
-    derp:
-      server:
-        enabled: false
-      urls:
-        - https://controlplane.tailscale.com/derpmap/default
-      paths:
-        - /etc/headscale/derp.yaml
-    ```
-
-=== "Provide custom DERP servers"
-
-    The following sample `derp.yaml` references two custom regions (`custom-east` with ID 900 and `custom-west` with ID 901)
-    with one custom DERP server in each region. Each DERP server offers DERP relay via HTTPS on tcp/443, support for captive
-    portal checks via HTTP on tcp/80 and STUN on udp/3478. See the definitions of
-    [DERPMap](https://pkg.go.dev/tailscale.com/tailcfg#DERPMap),
-    [DERPRegion](https://pkg.go.dev/tailscale.com/tailcfg#DERPRegion) and
-    [DERPNode](https://pkg.go.dev/tailscale.com/tailcfg#DERPNode) for all available options.
-
-    ```yaml title="derp.yaml"
-    regions:
-      900:
-        regionid: 900
-        regioncode: custom-east
-        regionname: My region (east)
-        nodes:
-          - name: 900a
-            regionid: 900
-            hostname: derp900a.example.com
-            ipv4: 198.51.100.1
-            ipv6: 2001:db8::1
-            canport80: true
-      901:
-        regionid: 901
-        regioncode: custom-west
-        regionname: My Region (west)
-        nodes:
-          - name: 901a
-            regionid: 901
-            hostname: derp901a.example.com
-            ipv4: 198.51.100.2
-            ipv6: 2001:db8::2
-            canport80: true
-    ```
-
-    Use the following configuration to only serve the two DERP servers from the above `derp.yaml`:
-
-    ```yaml title="config.yaml" hl_lines="5 6"
-    derp:
-      server:
-        enabled: false
-      urls: []
-      paths:
-        - /etc/headscale/derp.yaml
-    ```
-
-Independent of the custom DERP map, you may choose to [enable the embedded DERP server and have it automatically added
-to the custom DERP map](#enable-embedded-derp).
-
-### Verify clients
-
-Access to DERP serves can be restricted to nodes that are members of your Tailnet. Relay access is denied for unknown
-clients.
-
-=== "Embedded DERP"
-
-    Client verification is enabled by default.
-
-    ```yaml title="config.yaml" hl_lines="3"
-    derp:
-      server:
-        verify_clients: true
-    ```
-
-=== "3rd-party DERP"
-
-    Tailscale's `derper` provides two parameters to configure client verification:
-
-    - Use the `-verify-client-url` parameter of the `derper` and point it towards the `/verify` endpoint of your
-      Headscale server (e.g `https://headscale.example.com/verify`). The DERP server will query your Headscale instance
-      as soon as a client connects with it to ask whether access should be allowed or denied. Access is allowed if
-      Headscale knows about the connecting client and denied otherwise.
-    - The parameter `-verify-client-url-fail-open` controls what should happen when the DERP server can't reach the
-      Headscale instance. By default, it will allow access if Headscale is unreachable.
-
-## Check DERP server connectivity
-
-Any Tailscale client may be used to introspect the DERP map and to check for connectivity issues with DERP servers.
-
- Display DERP map: `tailscale debug derp-map`
- Check connectivity with the embedded DERP[^1]:`tailscale debug derp headscale`
-
-Additional DERP related metrics and information is available via the [metrics and debug
-endpoint](./debug.md#metrics-and-debug-endpoint).
-
-## Limitations
-
- The embedded DERP server can't be used for Tailscale's captive portal checks as it doesn't support the `/generate_204`
-  endpoint via HTTP on port tcp/80.
- There are no speed or throughput optimisations, the main purpose is to assist in node connectivity.
-

-# OpenID Connect
+# Configuring headscale to use OIDC authentication

-Headscale supports authentication via external identity providers using OpenID Connect (OIDC). It features:
+In order to authenticate users through a centralized solution one must enable the OIDC integration.

- Auto configuration via OpenID Connect Discovery Protocol
- [Proof Key for Code Exchange (PKCE) code verification](#enable-pkce-recommended)
- [Authorization based on a user's domain, email address or group membership](#authorize-users-with-filters)
- Synchronization of [standard OIDC claims](#supported-oidc-claims)
+Known limitations:

-Please see [limitations](#limitations) for known issues and limitations.
+- No dynamic ACL support
+- OIDC groups cannot be used in ACLs

-## Configuration
+## Basic configuration

-OpenID requires configuration in Headscale and your identity provider:
+In your `config.yaml`, customize this to your liking:

- Headscale: The `oidc` section of the Headscale [configuration](configuration.md) contains all available configuration
-  options along with a description and their default values.
- Identity provider: Please refer to the official documentation of your identity provider for specific instructions.
-  Additionally, there might be some useful hints in the [Identity provider specific
-  configuration](#identity-provider-specific-configuration) section below.
-
-### Basic configuration
-
-A basic configuration connects Headscale to an identity provider and typically requires:
-
- OpenID Connect Issuer URL from the identity provider. Headscale uses the OpenID Connect Discovery Protocol 1.0 to
-  automatically obtain OpenID configuration parameters (example: `https://sso.example.com`).
- Client ID from the identity provider (example: `headscale`).
- Client secret generated by the identity provider (example: `generated-secret`).
- Redirect URI for your identity provider (example: `https://headscale.example.com/oidc/callback`).
-
-=== "Headscale"
-
-    ```yaml
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-    ```
-
-=== "Identity provider"
-
-    - Create a new confidential client (`Client ID`, `Client secret`)
-    - Add Headscale's OIDC callback URL as valid redirect URL: `https://headscale.example.com/oidc/callback`
-    - Configure additional parameters to improve user experience such as: name, description, logo, …

-Proof Key for Code Exchange (PKCE) adds an additional layer of security to the OAuth 2.0 authorization code flow by
-preventing authorization code interception attacks, see: <https://datatracker.ietf.org/doc/html/rfc7636>. PKCE is
-recommended and needs to be configured for Headscale and the identity provider alike:
-
-=== "Headscale"
-
-    ```yaml hl_lines="5-6"
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-      pkce:
-        enabled: true
-    ```
-
-=== "Identity provider"
-
-    - Enable PKCE for the headscale client
-    - Set the PKCE challenge method to "S256"
-
-### Authorize users with filters
-
-Headscale allows to filter for allowed users based on their domain, email address or group membership. These filters can
-be helpful to apply additional restrictions and control which users are allowed to join. Filters are disabled by
-default, users are allowed to join once the authentication with the identity provider succeeds. In case multiple filters
-are configured, a user needs to pass all of them.
-
-=== "Allowed domains"
-
-    - Check the email domain of each authenticating user against the list of allowed domains and only authorize users
-      whose email domain matches `example.com`.
-    - A verified email address is required [unless email verification is disabled](#control-email-verification).
-    - Access allowed: `alice@example.com`
-    - Access denied: `bob@example.net`
-
-    ```yaml hl_lines="5-6"
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-      allowed_domains:
-        - "example.com"
-    ```
-
-=== "Allowed users/emails"
-
-    - Check the email address of each authenticating user against the list of allowed email addresses and only authorize
-      users whose email is part of the `allowed_users` list.
-    - A verified email address is required [unless email verification is disabled](#control-email-verification).
-    - Access allowed: `alice@example.com`, `bob@example.net`
-    - Access denied: `mallory@example.net`
-
-    ```yaml hl_lines="5-7"
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-      allowed_users:
-        - "alice@example.com"
-        - "bob@example.net"
-    ```
-
-=== "Allowed groups"
-
-    - Use the OIDC `groups` claim of each authenticating user to get their group membership and only authorize users
-      which are members in at least one of the referenced groups.
-    - Access allowed: users in the `headscale_users` group
-    - Access denied: users without groups, users with other groups
-
-    ```yaml hl_lines="5-7"
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-      scope: ["openid", "profile", "email", "groups"]
-      allowed_groups:
-        - "headscale_users"
-    ```
-
-### Control email verification
-
-Headscale uses the `email` claim from the identity provider to synchronize the email address to its user profile. By
-default, a user's email address is only synchronized when the identity provider reports the email address as verified
-via the `email_verified: true` claim.
-
-Unverified emails may be allowed in case an identity provider does not send the `email_verified` claim or email
-verification is not required. In that case, a user's email address is always synchronized to the user profile.
-
-```yaml hl_lines="5"
+```yaml title="config.yaml"

+    method: S256
+
+  # If `strip_email_domain` is set to `true`, the domain part of the username email address will be removed.
+  # This will transform `first-name.last-name@example.com` to the user `first-name.last-name`
+  # If `strip_email_domain` is set to `false` the domain part will NOT be removed resulting to the following
+  # user: `first-name.last-name.example.com`
+  strip_email_domain: true
 ```

-### Customize node expiration
+## Azure AD example

-The node expiration is the amount of time a node is authenticated with OpenID Connect until it expires and needs to
-reauthenticate. The default node expiration can be configured via the top-level `node.expiry` setting.
+In order to integrate headscale with Azure Active Directory, we'll need to provision an App Registration with the correct scopes and redirect URI. Here with Terraform:

-=== "Customize node expiration"
+```hcl title="terraform.hcl"
+resource "azuread_application" "headscale" {
+  display_name = "Headscale"

-    ```yaml hl_lines="2"
-    node:
-      expiry: 30d   # Use 0 to disable node expiration
-    ```
+  sign_in_audience = "AzureADMyOrg"
+  fallback_public_client_enabled = false

-=== "Use expiration from Access Token"
+  required_resource_access {
+    // Microsoft Graph
+    resource_app_id = "00000003-0000-0000-c000-000000000000"

-    Please keep in mind that the Access Token is typically a short-lived token that expires within a few minutes. You
-    will have to configure token expiration in your identity provider to avoid frequent re-authentication.
-
-    ```yaml hl_lines="5"
-    oidc:
-      issuer: "https://sso.example.com"
-      client_id: "headscale"
-      client_secret: "generated-secret"
-      use_expiry_from_token: true
-    ```
-
-!!! tip "Expire a node and force re-authentication"
-
-    A node can be expired immediately via:
-
-    ```console
-    headscale node expire -i <NODE_ID>
-    ```
-
-### Reference a user in the policy
-
-You may refer to users in the Headscale policy via:
-
- Email address
- Username
- Provider identifier (this value is currently only available from the [API](api.md), database or directly from your
-  identity provider)
-
-!!! note "A user identifier in the policy must contain a single `@`"
-
-    The Headscale policy requires a single `@` to reference a user. If the username or provider identifier doesn't
-    already contain a single `@`, it needs to be appended at the end. For example: the Headscale username `ssmith` has
-    to be written as `ssmith@` to be correctly identified as user within the policy.
-
-    Ensure that the Headscale username itself does not end with `@`.
-
-!!! warning "Email address or username might be updated by users"
-
-    Many identity providers allow users to update their own profile. Depending on the identity provider and its
-    configuration, the values for username or email address might change over time. This might have unexpected
-    consequences for Headscale where a policy might no longer work or a user might obtain more access by hijacking an
-    existing username or email address.
-
-!!! tip "Howto use the provider identifier in the policy"
-
-    The provider identifier uniquely identifies an OIDC user and a well-behaving identity provider guarantees that this
-    value never changes for a particular user. It is usually an opaque and long string and its value is currently only
-    available from the [API](api.md), database or directly from your identity provider).
-
-    Use the [API](api.md) with the `/api/v1/user` endpoint to fetch the provider identifier (`providerId`). The value
-    (be sure to append an `@` in case the provider identifier doesn't already contain an `@` somewhere) can be used
-    directly to reference a user in the policy. To improve readability of the policy, one may use the `groups` section
-    as an alias:
-
-    ```json
-    {
-      "groups": {
-        "group:alice": [
-          "https://soo.example.com/oauth2/openid/59ac9125-c31b-46c5-814e-06242908cf57@"

-## Limitations

- Support for OpenID Connect aims to be generic and vendor independent. It offers only limited support for quirks of
-  specific identity providers.
- OIDC groups cannot be used in ACLs.
- The username provided by the identity provider needs to adhere to this pattern:
-    - The username must be at least two characters long.
-    - It must only contain letters, digits, hyphens, dots, underscores, and up to a single `@`.
-    - The username must start with a letter.

- [Authentik](#authentik)
- [Kanidm](#kanidm)
- [Keycloak](#keycloak)
+## Google OAuth Example

-### Authelia
+In order to integrate headscale with Google, you'll need to have a [Google Cloud Console](https://console.cloud.google.com) account.

-Authelia is fully supported by Headscale.
+Google OAuth has a [verification process](https://support.google.com/cloud/answer/9110914?hl=en) if you need to have users authenticate who are outside of your domain. If you only need to authenticate users from your domain name (ie `@example.com`), you don't need to go through the verification process.

-### Authentik
+However if you don't have a domain, or need to add users outside of your domain, you can manually add emails via Google Console.

- Authentik is fully supported by Headscale.
- [Headscale does not support JSON Web Encryption](https://github.com/juanfont/headscale/issues/2446). Leave the field
-  `Encryption Key` in the providers section unset.
- See Authentik's [Integrate with Headscale](https://integrations.goauthentik.io/networking/headscale/)
-
-### Google OAuth
-
-!!! warning "No username due to missing preferred_username"
-
-    Google OAuth does not send the `preferred_username` claim when the scope `profile` is requested. The username in
-    Headscale will be blank/not set.
-
-In order to integrate Headscale with Google, you'll need to have a [Google Cloud
-Console](https://console.cloud.google.com) account.
-
-Google OAuth has a [verification process](https://support.google.com/cloud/answer/9110914?hl=en) if you need to have
-users authenticate who are outside of your domain. If you only need to authenticate users from your domain name (ie
-`@example.com`), you don't need to go through the verification process.
-
-However if you don't have a domain, or need to add users outside of your domain, you can manually add emails via Google
-Console.
-
-#### Steps
+### Steps

 1. Go to [Google Console](https://console.cloud.google.com) and login or create an account if you don't have one.
-1. Create a project (if you don't already have one).
-1. On the left hand menu, go to `APIs and services` -> `Credentials`
-1. Click `Create Credentials` -> `OAuth client ID`
-1. Under `Application Type`, choose `Web Application`
-1. For `Name`, enter whatever you like
-1. Under `Authorised redirect URIs`, add Headscale's OIDC callback URL: `https://headscale.example.com/oidc/callback`
-1. Click `Save` at the bottom of the form
-1. Take note of the `Client ID` and `Client secret`, you can also download it for reference if you need it.
-1. [Configure Headscale following the "Basic configuration" steps](#basic-configuration). The issuer URL for Google
-   OAuth is: `https://accounts.google.com`.
-
-### Kanidm
-
- Kanidm is fully supported by Headscale.
- Groups for the [allowed groups filter](#authorize-users-with-filters) need to be specified with their full SPN, for
-  example: `headscale_users@sso.example.com`.
- Kanidm sends the full SPN (`alice@sso.example.com`) as `preferred_username` by default. Headscale stores this value as
-  username which might be confusing as the username and email fields now contain values that look like an email address.
-  [Kanidm can be configured to send the short username as `preferred_username` attribute
-  instead](https://kanidm.github.io/kanidm/stable/integrations/oauth2.html#short-names):
-    ```console
-    kanidm system oauth2 prefer-short-username <client name>
+2. Create a project (if you don't already have one).
+3. On the left hand menu, go to `APIs and services` -> `Credentials`
+4. Click `Create Credentials` -> `OAuth client ID`
+5. Under `Application Type`, choose `Web Application`
+6. For `Name`, enter whatever you like
+7. Under `Authorised redirect URIs`, use `https://example.com/oidc/callback`, replacing example.com with your headscale URL.
+8. Click `Save` at the bottom of the form
+9. Take note of the `Client ID` and `Client secret`, you can also download it for reference if you need it.
+10. Edit your headscale config, under `oidc`, filling in your `client_id` and `client_secret`:
+    ```yaml title="config.yaml"
+    oidc:
+      issuer: "https://accounts.google.com"
+      client_id: ""
+      client_secret: ""
+      scope: ["openid", "profile", "email"]
    ```
-    Once configured, the short username in Headscale will be `alice` and can be referred to as `alice@` in the policy.

-### Keycloak
-
-Keycloak is fully supported by Headscale.
-
-#### Additional configuration to use the allowed groups filter
-
-Keycloak has no built-in client scope for the OIDC `groups` claim. This extra configuration step is **only** needed if
-you need to [authorize access based on group membership](#authorize-users-with-filters).
-
- Create a new client scope `groups` for OpenID Connect:
-    - Configure a `Group Membership` mapper with name `groups` and the token claim name `groups`.
-    - Add the mapper to at least the UserInfo endpoint.
- Configure the new client scope for your Headscale client:
-    - Edit the Headscale client.
-    - Search for the client scope `group`.
-    - Add it with assigned type `Default`.
- [Configure the allowed groups in Headscale](#authorize-users-with-filters). How groups need to be specified depends on
-  Keycloak's `Full group path` option:
-    - `Full group path` is enabled: groups contain their full path, e.g. `/top/group1`
-    - `Full group path` is disabled: only the name of the group is used, e.g. `group1`
-
-### Microsoft Entra ID
-
-In order to integrate Headscale with Microsoft Entra ID, you'll need to provision an App Registration with the correct
-scopes and redirect URI.
-
-[Configure Headscale following the "Basic configuration" steps](#basic-configuration). The issuer URL for Microsoft
-Entra ID is: `https://login.microsoftonline.com/<tenant-UUID>/v2.0`. The following `extra_params` might be useful:
-
- `domain_hint: example.com` to use your own domain
- `prompt: select_account` to force an account picker during login
-
-When using Microsoft Entra ID together with the [allowed groups filter](#authorize-users-with-filters), configure the
-Headscale OIDC scope without the `groups` claim, for example:
-
-```yaml
-oidc:
-  scope: ["openid", "profile", "email"]
-```
-
-Groups for the [allowed groups filter](#authorize-users-with-filters) need to be specified with their group ID(UUID) instead
-of the group name.
-
-## Switching OIDC providers
-
-Headscale only supports a single OIDC provider in its configuration, but it does store the provider identifier of each user. When switching providers, this might lead to issues with existing users: all user details (name, email, groups) might be identical with the new provider, but the identifier will differ. Headscale will be unable to create a new user as the name and email will already be in use for the existing users.
-
-At this time, you will need to manually update the `provider_identifier` column in the `users` table for each user with the appropriate value for the new provider. The identifier is built from the `iss` and `sub` claims of the OIDC ID token, for example `https://id.example.com/12340987`.
+You can also use `allowed_domains` and `allowed_users` to restrict the users who can authenticate.
