Hi there, we have the following setup: Official Discourse 2.5.0 ([ 3f7658cc6e ]) with the discourse-saml plugin (commit 230a58b), Keycloak (10.0.2) as Identity Provider Our Identity Provider is set up to use the url https://discourse.our-domain.xxx/auth/saml/slo as Logout Service POST Binding UR…

We’re not handling the saml_uid session value in our plugin. It’s handled by the omniauth-saml gem itself. So I’m not sure about why you have an empty value in session["saml_uid"]. You may need to report the issue in omniauth gem. Also, none of the customers have reported an issue in SLO yet.

I have recognized the same thing: 2 applications (discourse and another one. lets name it X) connected to keycloak with SAML. Logout on discourse. The user is also logged out on X and can’t do anything there. Logout on X. The session on keycloak is gone but the user stays online in discourse Even…

Would it be possible to validate if the saml session is still alive? See answer above @vinothkannans

Sarebbe possibile verificare se la sessione SAML è ancora attiva? Vedi la risposta sopra @vinothkannans
