I bound my server to AD using the Bombich whitepaper and it seemed to be working normally. I wasn’t able to look at it for a few weeks (vacation) and afterward kerberized services were unavailable and would fail promptly after a reboot. Shutdown would fail, and from the GUI, applications wouldn’t launch or stopped responding.
As soon as I unbound from Active Directory and destroyed the Kerberos realm, all these apps started responding properly. Sorry if this is rather generalized–I’m not a full-time systems admin, but I want this to work!
