This weekend we moved our samba PDC to a new machine. Now we are
having a few issues with not being able to join new computers to the
domain and some users cannot change their passwords. People can still
login and such though. Here is a brief synopsis:
Old server was named roark IP 10.8.2.3. It housed mail, ldap, samba,
and a few other things. Was fedora 11 with samba samba-3.4.7.
New server is Centos 5.5 with 3.0.33 originally but I upgraded it to
the "samba3x" package and got a whopping 3.3.8 version. IP 10.8.3.4
Both old and new have the BDC set at 10.8.2.2
Everything worked until the move this weekend... I know.. famous last
words. ;)
This weekend we migrated all the user files to the new machine, copied
over /etc/samba/*, edited the ldap portion of smb.conf accordingly,
changed all the other servers (we have about a dozen or so home
servers for various divisions) to reflect the new IP of the new server
and updated DNS accordingly. All seemed fine as we were able to
login/logout and get to all the shares just fine. the problem came
when users went to change their passwords using the windows method
(CTRL+ALT+DEL -> change password), which previously worked. Also we
are unable to join new computers to the domain at all. Although, users
on the same vlan (10.8.3.X) as roark are able to change their
passwords it seems. This is odd since all but 3 of the users are on
roark as their home server. The other 3 are on a seperate server but
are still able to change their passwords. The error that users get
when trying to change their password or join a new pc to the domain is
"Domain ADMIN not found" or something along those lines.
I have tried everything I can think of to get this resolved. I have
made sure the SID stayed the same on roark, rejoined the outlying
servers to the domain, reset the smbpasswd ldap password, and scoured
every log file I can find. All to no avail. I am including a few
configs in hopes that someone can help guide me into fixing this issue.
I am also considering moving the PDC back to a fedora machine (fedora
13 to be exact) so that it is more like the original machine and can
get the same branch of samba.
I hope someone out there can guide me in the correct direction to fix
this. :)

And this is odd, I bumped the logging level to 10 and did some digging.
I am getting this on ALL the machines. INCLUDING the PDC:
ADMIN(1) current master browser = UNKNOWN
I have googled for that error but to no avail. Seems others have asked
it but no one answered.
