Logout page not alsways the Authentik Choice one

[pct06]

Hi
I am quite new in SSO and implented SSO with Beszel, Immich, Portainer and Arcane.

With Immich and Portainer, when logging off the app, I got the below screen :

For Beszel and Arcane, I am always back to their respective Login Page (choice between app login/passwd or OAuth login) and never to the above one, and I therefore also remain logged to Authentik.

I have followed the Integration documentation for all of these apps and I am unable to understand why the logout is different ?

Thanks for your help.

Portainer and Immich are pulling the logout URL from authentik's configuration URL (wellknown URL) and using it for logout. Beszel and Arcane aren't doing this. It's different implementations of how to handle OIDC on their side.

If you open one of your configured OAuth providers, you'll see a logout URL. That's the URL that Portainer and Immich are extracting and redirecting you to upon logout.

You can also open up a configuration URL for one of your OAuth providers: https://<your authentik FQDN>/application/o/<oauth provider slug>/.well-known/openid-configuration

Here you can see the information that's passed to the application from authentik. Beszel and Arcane aren't programmed/configured to use that information.
