[Samba] Winbind & Multiple AD servers repost was unusual winbind crashes

[Brett Stevens]

So far we have been working well for a week now. We are using Samba 3.02a on
suse 9. Authentication is against an win3k AD. Apart from a Kerberos ticket
expiring, (a croned restart fixes this) we have one new problem
We found we needed an additional AD server as the primary begun to fail on a
regular basis. So we added one. Now this new server grabs the authentication
requests before the old one and when it does that winbind crashes out with
the following log messages

Ive just begun to investigate this problem but as we are in production with
this error I thought Id drop a quick line to the group and see if any one
knows about this error.

Thanks in advance
