I don't have a krb5.conf.  I think it uses DNS to find the Kerberos servers.

I have attached the excerpt from my log.winbindd from when the problem
started.  The messages at the end go on for another 30 minutes until the
winbindd service was reset.

The server xxx at XXX.XXX in the logs isn't a Domain Controller.  I'm not
really sure why it's even being referenced in this log file.
