samba - Sep 2004 - winbind is loosing domain prefix

Hi,

we're using the SerNet-release of samba 3.0.7 running on SLES8. Our 
samba server is running as domain member server (security=ADS) in our 
w2k domain. On monday we migrated from 3.0.4 to 3.0.7. Since then 
winbind is trying to relsolve usernames without the domain-prefex and 
fails. See below:
log.winbindd:
...
[2004/09/22 06:54:24, 1] nsswitch/winbindd_user.c:winbindd_getpwnam(159)
  user 'm019u026' does not exist
[2004/09/22 06:54:24, 1] nsswitch/winbindd_user.c:winbindd_getpwnam(159)
  user 'm019u026' does not exist
[2004/09/22 06:54:24, 1] nsswitch/winbindd_user.c:winbindd_getpwnam(159)
  user 'M019U026' does not exist
...

It should be SCHARRNET+m019u026. And in addition i get the following 
errors in log.winbind.
...
[2004/09/22 06:17:12, 1] nsswitch/winbindd_ads.c:ads_cached_connection(81)
  ads_connect for domain SCHARRNET failed: Invalid credentials
...

  spnego_gen_negTokenTarg failed: Unknown error -1765328347
...

If we restart winbindd, nmbd and smbd samba runs normal again (until 
next restart). Can anybody give us a hint what the problem is and how we 
can fix it?

Regards

Thorsten
