[Samba] Re: SMBD and Winbind Errors

I've been having a similar issue with winbindd hanging up enumerating
users and groups.
Here were my symptoms:
log.winbindd showed that winbindd was connecting to servers that did not
respond (no error, but using tail -f on the log at debug 10 while
running either wbinfo -u/g or getent passwd/group showed a stop of
net lookup dc <OTHER_DOMAIN> listed IP's that are not available (can't
ping, nslookup or traceroute).
Existing connections work, new connections by any means did not.
net lookup dc <OTHER_DOMAIN>
net lookup master <OTHER_DOMAIN>
Made sure that master was in list of dc's.
wbinfo -I <IP_OF_MASTER>
made sure both records exist.
Edited /etc/samba/lmhosts to have
added 'name resolution order = lmhosts wins bcast' to smb.conf
I did this for the domain I am in and all domains I have trusts with.
This has cut the time it takes for winbindd to enumerate all the users
on my corporate domains from several hours to about 3-6 mins for users.
I don't know if this is true or not, but my suspicion is that (at least
for NT4 domains) winbind is relying on the PDC to tell it which machines
are dc's. On some domains, dead accounts in the server manager seem to
be screwing this up.
