Hi People,

samba-3.0.9-1.3E.3 joined to AD domain, running winbind on RHEL 3

The Problem - Every now and then samba seems to 'lose' the domain - i.e.
wbinfo -u/g will not list users/groups but after a couple of goes it
does eventually list them and then generally it's all ok.  While this is
happening users are prompted for a username/password to access the box
(normally just lets them straight in).  Seems to randomly happen but
sometimes notable when samba/winbind is restarted.  Sometimes it appears
to automagically fix itself.

What could be causing this?

<Snip of main parts of SMB.conf>
workgroup = AUSTRALIA
server string = Linux Box
printcap name = /etc/printcap
load printers = yes
cups options = raw
log file = /var/log/samba/smbd.log
max log size = 50
security = ADS
   realm = <my AD Domain>
   winbind uid = 10000-20000
   winbind gid = 10000-20000
   winbind enum users = yes
   winbind enum groups = yes
   winbind use default domain = yes
   winbind separator = +
   template shell = /bin/bash
   template homedir = /home/%U
   encrypt passwords = yes
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   dns proxy = no

   force create mask = 0775
   force directory mask = 0774

Nsswitch.conf includes winbind for user/group auth.
Winbind is set to restart with smb.
