[Samba] modify permissions fail on new file server.

I'm using winbindd with samba 3.0.1.  Everything starts up as expected 
and tests return the expected results (wbinfo and getent).   Files 
created via windows  clients are create with the proper ownership and 
group membership.  When I attempt to modify the permissions via the 
windows security tab (add another group, change ownership for example) 
I'll get a win pop up saying 'permission denied" and the below out put 
will be wrote out to the machine.log.  From a unix shell I can change 
perms over NFS.

  fetch uid from cache 3041 -> S-1-5-21-861567501-1262210171-1417111838-1275

[2003/12/31 16:46:07, 3] smbd/error.c:error_packet(94)
  error string = Operation not supported

As the file appears from UNIX:
drwxr-xr-x    2 greg     Domain Users       96 Dec 31 16:29 foo
The dir this is in has a mode of 777 and is owned by 'greg'.

Samba was built with:
configure --with-ads --with-pam --with-winbind-auth-challenge 
--with-acl-support --with-winbind  --prefix=/opt/samba

The physical setup is as such:

SAMBA-SERVER has 2 interfaces on it,  one samba listens on,  the other 
is used for NFS traffic.
NFS-SERVER has the physical drives attached to it,  using veritas 
cluster file system version 3.x
SAMBA-SERVER mounts the drives under /n/fire/array.  this is also 
defined within smb.conf.

My question:  Why can I not change ACL's on the file system?  Is there 
something I can do to correct this?
I see it mentions to many ACE entries to convert to posix, I used a 
local XFS file system a while ago and
 things seemed to work as expected,  but this is no longer an option.

Thanks for your input,
