[Samba] NMBD going down almost immediately after startup

[Bart]

Hi,
I'm having problems getting nmbd running.
Server is RH7.3 + ACL patches.

The problem is that the nmbd deamon crashes with the following error :

[2002/10/09 04:42:43, 0] nmbd/nmbd.c:main(794)
  Netbios nameserver version 2.2.5 started.

  Got SIGTERM: going down...

smb.conf configuration is exactly the same as on another test server and it
works over there.

Could there be a problem with 'pam' that causes these issues ?

wbinfo -t returns : secret is good
wbinfo -g returns all PDC+groups
wbinfo -u returns all PDC+users
smbclient -L PDC returns pdc shares

What is probably going wrong and what can I do to check certain settings or
fix my problem ?
Any suggestions/solutions anyone ?

Thanks in advance

Bart
