Remove `dns.use_username_in_magic_dns` configuration option [#2020](https://github.com/juanfont/headscale/pull/2020) - Having usernames in magic DNS is no longer possible. -- Redo OpenID Connect configuration [#2020](https://github.com/juanfont/headscale/pull/2020) - - `strip_email_domain` has been removed, domain is _always_ part of the username for OIDC. - - Users are now identified by `sub` claim in the ID token instead of username, allowing the username, name and email to be updated. - - User has been extended to store username, display name, profile picture url and email. - - These fields are forwarded to the client, and shows up nicely in the user switcher. - - These fields can be made available via the API/CLI for non-OIDC users in the future. -
