samba - Feb 2003 - getent groups doesn't return all groups - reported as a bug but was there a fix?

I have been doing some google searchings and more research about my problem:

My problems seems to be the same one - getent group only returns unix groups and
domain admins group.  My samba server is hpux 11, samba 2.2.7a.  Was this
confirmed to be a bug?
