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!

Dale,
I was afraid of that. We we're forced to upgrade from 3.5.x because of a
reoccurring Winbind issue but I'm a bit disappointed to see that 3.6.x
introduces a idmap/rid issues. I guess we just traded one for another.
Do you think un-joining and then re-joining the existing system could fix this?
Thanks.

Kevin,
3.6.x has had several issues with idmap rid. I was hit with this one:
https://bugzilla.samba.org/show_bug.cgi?id=8676 . Searching for idmap rid
issues with 3.6.x will reveal others as well.
Someone indicated that rejoining the domain would fix this issue. As it so
happened, I had to rebuild one of the servers. After joining the rebuilt
system to the domain, it has worked flawlessly ever since. So, it appears the
problem with rid and some of the other idmap backends is somehow related to
upgrading, as newly joined systems work as expected.

Hello all.
We are running Samba 3.6.6 on a Debian 6.0.6 server. We made the upgrade from
3.6.5 to 3.6.5 about a week ago and ever since we have lost the ability to map

However, I can successfully return login information with winbind:

'getent passwd' will only return the local users from /etc/passwd.
And the relevant section of smb.conf:
