[feature req] add OIDC authentication + roles

[andrewzah]

https://swagger.io/docs/specification/authentication/openid-connect-discovery/

This would allow things like SSO through an external service like Keycloak, which generates .well-known automatically. A generic OIDC authenticator is preferable to service-specific logins like Google, Facebook, etc.

One way to do this would be to have multiple Authenticators, like an OIDCAuthenticator and a LocalAuthenticator, which is the current behavior. Having an option to disable the LocalAuthenticator entirely and only populate users through the OIDCAuthenticator would be preferable.

For admins: One solution is either the access token or the auth token could have a roles object, which would look for a role named admin.

Thanks! Multiple authentication backend will be implemented at some point, but the priority now is to decide how to work around the Subsonic API limitations regarding authentication: #202 (comment).

Bumping this as something I'm still keen to see in Navidrome.
Understand this is waiting for the revisions to the API, but very much looking forward to this.

This bot is a bit overeager, the issue is still very much relevant.

One way to handle this would be to provide separate Subsonic authentication passwords. A password could be autogenerated when a user gets created. While this password will be stored in database it would only be used for subsonic authentication and would not allow login into the UI or access anything not supported by subsonic.

The main user password could then be properly hashed.

This does not fully eliminate all risks, but limits the impact of the password. Especially for admin accounts, but also normal accounts.

[andrewzah]

Agreed, generating a random token for subsonic auth seems like a reasonable way to address this.

Indeed, SSO via OIDC is thanks to Authentik and Authelia easily embeddable.

[DDriggs00]

One way this could work is using app passwords for subsonic, like nextcloud uses for Caldav when it is using OIDC.

Looking forward for OIDC support with Authentik, too
