[Samba] Changing file ownership from Windows

[Marek Drápal]

Hi all,

I've spent lot of time with reading various HOWTOs and mailing lists, but
after all of that I can't change file ownership from Windows XP...
I'm running Samba (3.0.11) PDC on a machine with EXT3 ACLs. From the admin 
account I can change file permissions, add/remove ACL groups and their 
permissions, but I'm unable to change the main unix group or user ownership.
I'll really appreciate whatever hints.

Thanks
