samba - Sep 2004 - wb_getgrgid: failed to locate gid == 10002

Hi!

samba 3.0.6 
AIX 5.1 ML5
AD 2003 native mode

I have big problems to get AIX auth against a AD with winbind
The problem is the primary grouplookup

idefix#lsuser adminanla
adminanla id=10000 pgrp=Domain Users

idefix#id adminanla 
uid=10000(adminanla) gid=10000


[2004/07/22 16:20:13, 3] nsswitch/winbindd_user.c:winbindd_getpwnam(124)
  [13174]: getpwnam adminanla
[2004/07/22 16:20:13, 3] nsswitch/winbindd_user.c:winbindd_getpwnam(124)
  [13174]: getpwnam adminanla
[2004/07/22 16:20:13, 3] nsswitch/winbindd_group.c:winbindd_getgrgid(348)
  [13174]: getgrgid 10000
[2004/07/22 16:20:13, 4] nsswitch/winbindd_acct.c:wb_getgrgid(544)
  wb_getgrgid: failed to locate gid == 10000


if we have less than 1000 users in the domain then the "id" works
but i get same error with "wb_getgrgid: failed"

wbinfo -a adminanla%password 
works

im stuck with this problem
there are no problem at all in a Linux box with pam
