winbind issues under Ubuntu

winbind issues under Ubuntu

winbind issues under Ubuntu

(OP)
Problem:
Trying to finish creation of Samba 3.3.2 domain server on new 9.04 Ubuntu server.  Did default Ubuntu installation of LAMP and Samba during installation.  Successfully edited smb.conf, built users, server and resources visible in smbclient and in windows test workstation.  Can login as different users, and join machines to the domain via windows.  However, the whole system was INCREDIBLY slow!

Question:
Started checking the log files and noticed I was getting winbind errors.  After starting samba & winbind, I get repeating errors in /var/log/samba/log.winbindd. (see file below)  I've searched many forums and sites for the error msgs and can't find references.  Can you clue me in why these are generated and where/what I need to reconfig?

FYI, log.winbindd and smb.conf is below.  Let me know if you need more resources.

Regards,
--mdutch

RE: winbind issues under Ubuntu

(OP)
Still having log.winbindd errors every 10-15 seconds...

With the help of a contributor, I changed

CODE

    auth methods = sam
to

CODE

    auth methods = sam winbind
and the error in log.winbindd
    saf_store: refusing to store 0 length domain or servername!
stopped appearing!  w00t!

But, I'm still getting Server stopped responding errors in log.winbindd:

Similar entries in log.wb-JAM2  (the domain winbind file)
