A rejoin unfortunately did not fix this issue and interestingly enough Samba failed to find a domain controller by any of the standard lookup means (hosts, lmhosts, WINS and with a broadcast) so I had to use the -s argument to manually specify the server in the 'net ads join' command. This probably signifies deeper issues.
Eventually I just used the current Sernet provided 3.6.9 packages which "resolved" the issue. What's so odd about this is that there is a nearly identical secondary host running the same version of Samba used for failover. No issues with the secondary. Go figure. --- Kevin Elliott Network Specialist City and Borough of Juneau, MIS (907) 586 - 0905 -----Original Message----- From: Dale Schroeder [mailto:d...@briannassaladdressing.com] Sent: Friday, November 30, 2012 10:55 AM To: Kevin Elliott Cc: 'samba@lists.samba.org' Subject: Re: [Samba] User is invalid on this system With what I've read and what I've seen with the rebuilds, there's a good chance the rejoin could fix your problem. That being said, there are no guarantees with winbind. It's the part of the Samba suite that has given me the most problems over the years, breaking existing configs almost every time its internal workings are changed. I wish you good luck!
