Today we've released UTM 9.414. The release is now available for all via Up2Date servers.
Can confirm, just been advised to rollback to 9.413 if I don't wish to re-authenticate against AD every 24 hours
Problem not solved, there's still the AD-SSO-Error
Our user got a "Authentication failed" message and no web access was possible (standard mode with AD SSO active).
I removed the UTM from the Active Directoy domain and deleted the UTMs computer account in the Active Directory. I then rejoined the domain and AD SSO was a back alive.
Apparently 9.501-5 has required admins to disconnect and rejoin ActiveDirectory for SSO to work. Has this version been tested for similar problems?
