[Samba] Winbind failure

[Michael Bann]

Folks,

I am setting up a server to use cups printing and samba to communicate 
with windows. Samba appeared to be working for a little while and then 
for some reason stopped working. Looking at the log files I see the 
following:

[2007/07/10 12:49:16, 0] smbd/server.c:main(986)
  standard input is not a socket, assuming -D option
[2007/07/10 12:49:16, 0] 
nsswitch/winbindd_cache.c:initialize_winbindd_cache(2221)
  initialize_winbindd_cache: clearing cache and re-creating with version 
number 1
[2007/07/10 12:49:16, 0] nsswitch/winbindd_util.c:init_domain_list(513)
  Could not fetch our SID - did we join?
[2007/07/10 12:49:16, 0] nsswitch/winbindd.c:main(1088)
  unable to initalize domain list
[2007/07/10 12:49:16, 0] printing/nt_printing.c:nt_printing_init(650)
  nt_printing_init: error checking published printers: WERR_ACCESS_DENIED

The command "getent passwd" lists users on the domain.  The command "net 
ads testjoin" results in "Join is OK".  Testparm says that the 
configuration file is fine. "net getlocalsid" and "net getlocalsid cems" 
both return a sid value. Klist shows valid tickets for my domain. Doing 
a /etc/init.d/smb restart shows that winbind starts up "ok" but will 
always "fail" on shutdown. This leads me to believe that it's not 
actually starting "ok", or that it is but it's crashing quickly thereafter.

Does anyone have ideas about why this might be happening?

Thanks,

Michael
