Sorry, I was a little confused. I think the term "primary group"
generally means the primary group of groups which an user belongs to.

As far as I examined there is no way to display/change the owner group
of files via Samba. Also in Samba 3.x, we cannot set any groups to
an owner of a file.

I think it's difficult to implement because Windows does not have the
semantics of "owner group".
