Fredrik Ekre	5d8a2c25ea	OIDC: Query userinfo endpoint before verifying user ... This patch includes some changes to the OIDC integration in particular: - Make sure that userinfo claims are queried *before* comparing the user with the configured allowed groups, email and email domain. - Update user with group claim from the userinfo endpoint which is required for allowed groups to work correctly. This is essentially a continuation of #2545. - Let userinfo claims take precedence over id token claims. With these changes I have verified that Headscale works as expected together with Authelia without the documented escape hatch [0], i.e. everything works even if the id token only contain the iss and sub claims.

Florian Preinstorfer	d461db3abd	Refactor OpenID Connect documentation ... Restructure and rewrite the OpenID Connect documentation. Start from the most minimal configuration and describe what needs to be done both in Headscale and the identity provider. Describe additional features such as PKCE and authorization filters in a generic manner with examples. Document how Headscale populates its user profile and how it relates to OIDC claims. This is a revised version from the table in the changelog. Document the validation rules for fields and extend known limitations. Sort the provider specific section alphabetically and add a section for Authelia, Authentik, Kanidm and Keycloak. Also simplify and rename Azure to Entra ID. Update the description for the oidc section in the example configuration. Give a short explanation of each configuration setting. All documentend features were tested with Headscale 0.26 (using a fresh database each time) using the following identity providers: * Authelia * Authentik * Kanidm * Keycloak Fixes: #2295	2025-07-04 10:51:37 +02:00

Mustafa Enes Batur	bad783321e	Fix /machine/map endpoint vulnerability (#2642) ... * Improve map auth logic * Bugfix * Add comment, improve error message * noise: make func, get by node this commit splits the additional validation into a separate function so it can be reused if we add more endpoints in the future. It swaps the check, so we still look up by NodeKey, but before accepting the connection, we validate the known machinekey from the db against the noise connection. The reason for this is that when a node logs in or out, the node key is replaced and it will no longer be possible to look it up, breaking reauthentication.
