samba - Jun 2003 - 2.2.8a with XFS and LDAP - What should and wont work?

I have Samba 2.2.8a running on RH9 with XFS setup and most things appear to
be working but there are a couple of things not behaving as expected.

My account has been created on the server as a member of the Admisistrators
and Domain Admins groups.
I have the following line in by smb.conf file:-
domain admin group = " @"Domain Admins" "

Working
-------
Printing
Changing permissions on files/directories that I own
Adding machines to the domain automatically (using my account)

Not Working
-----------
Creating user accounts via the Win2K tools (I know from the Samba-Ldap-PDC
howto that this wont work)
I cannot take ownership of a file even if the file has the domain admins
group as full control.
I cannot change permissions of a file even if the domain admins group has
full control (which includes the change permissions right)

Should I be able to do the last two?

Thanks
