We have a Google Apps account that we use for most of our work. We also use AD FS 3.0 as an SSO provider to authenticate users. Everything works great with the sign in process. However when signing out, it all falls to pieces.
I followed a guide a long time ago to get it setup and the verified the settings with this guide and checked a few others and the settings should be correct.
When signing out from a Google page, we get redirected to our AD FS sign out url (https://<domainname>/adfs/ls/?wa=wsignout1.0)
, then get a message that says "You have been successfully signed out". However, going back to our custom sign in URL for Google (mail.domainname)
we are signed straight back into Google as if we didn't hit the sign out button.
I've done some digging around and apparently this is a larger issue. This post on Google Product Forum has the exact issue I am having and someone suggested to contact Google Support. After on the phone for about an hour with Google support, they decided that the issue was from our AD FS server running some kind of script that keeps us logged in and I should contact our web developer...
The problem is somewhere within AD FS but I cannot seem to figure it out and hoping someone has come across the same issue and would be able to provide some guidance.
