samba - Jan 2007 - Windows file security properties on a domain member server

Hello,

When viewing the Windows file security properties, for a file stored on
a Samba domain member server, should the ACL show the AD domain or the
Samba server as the domain?

If the ACL should show the AD domain, can someone point me at some
things to check?

The UID/GID assignments in Linux are as expected.

Any help is appreciated.
