Authentication Failing

Since installing the V17 beta I have been unable to get user authentication\identification working correctly for web client or user identification

I am able to log into the Sophos admin console or User portal using AD auth, however any firewall rule set to 'match users' blocks all traffic and the Captive Portal rejects all credentials with error "

User Bob@bob.local failed to login to Firewall through AD authentication mechanism from 192.168.8.8 because of wrong credentials


Authentication servers are configured correct and 'test connection' working. 

Currently on SFOS 17.0.0 RC-1
