[keycloak-user] SAML Identiy broker mode bypasses any authentication after logout

Hi, I have a spring-security based application that connects to keycloak via SAML. Keycloak itself is configured to connect via SAML to another external identity provider (so Keycloak is just the identity broker in this case). When I logout from my web application by going to https://<app_url>/saml/logout?local=false, a LogoutRequest is sent to keycloak, followed by a LogoutRequest to the external IDP. There is *no* LogoutResponse. Strangely, when I try to access my web application again, I am not asked to login and can access it as if the session is still valid. No AuthnRequest is seen in this case. What could be wrong? It seems that either the web application or the Keycloak is caching the session and not invalidating it upon a LogoutRequest. Maybe someone can help shed some light on this. Thanks, Pieter We empower scientists by building on open source software
