samba - Sep 2004 - winbind can't find sid

Hi all,

I've setup a Samba 3.0.6 with an Ldap backend on a Suse 9.1 system
it seems to work, but.....
I get the following error every 5 minuts in my winbind log

[2004/09/09 16:20:53, 1]
nsswitch/winbindd_util.c:winbindd_lookup_name_by_sid(502)
  Can't find domain from sid

any ideas,

Wisu
