samba - Dec 2004 - samba 3.09 pdc ldap usrmgr problem with viewing some groups

Hi sambatistas,
i just noticed a strange problem with usrmgr,
on my new pdc with my standart well tested smb.conf for smb pdc with ldap,
usrmgr  does only show  up  a few from the default groups,
i.e Domain Admins can be seen but not Administrators
i can browse that groups with a ldap client so i know everything went right
at the populate, i view from a win xp serv pack2 system
anybody else with simular problems?
Regards
