8.303 Upgrade lost AD auth

Hi,

Just done an update to 8.303 and lost AD authing for everything.

Http.log shows file="auth_adir.c" line="299" message="write: Connection refused" thus the request is blocked.

Input username and password for domain membership again, but comes back and says not connected to any domain. Rebooted, try again, the same.

Any pointers guys?

Rolling back changes now....

EDIT: Rolling back config not worked. Restoring VM now :-(
