KOHA logout not working (just refreshes page) when SSO Azure session has expired. To reproduce this: 1. Login to Koha staff side SSO (if you logout now it functions) 2. If I leave the session for an extended period of time (1+ hour) I can see the SSO session with azure has expired using KohaSite/Shibboleth.sso/Session 3. If i now try to logout of Koha, the Logout button just refreshes the staff interface and stays logged in. Log out is now only possible by closing the browser.
