Main fileserver.  Runs Ubuntu 8.04 LTS.  Uptime 180 days.  Also runs
samba joined to UFAD; this is a custom version of samba in
/depot/samba-3.3.2, not the system samba.  Using the system Kerberos.

Yesterday evening I did:

	apt-get update
	apt-get dist-upgrade
	reboot

This morning, samba is not working, as experienced from Windows clients.

The relevant error message seems to be in /depot/samba-3.3.2/var/log.wb-UFAD

These things seem to work:

	kinit [log in to unmask]
	klist
	/depot/samba-3.3.2/bin/net ads join -U "CLAS-ADM-BB"

The symptoms resemble this bug, but why would I suddenly start seeing them?

Things I've tried on the two versions:

	many restarts in various orders
	debugging flags -d 1, -d 10, -d 99

	# To reset state and logs between restarts
	find var -type f -print | xargs rm

	winbind separator = \\
	winbind separator = \

	recompile samba 3.3.2: no change

	install samba 3.5.2: Aborts at the net ads join

Thoughts?
