First question: do you have both "ntsec" and "smbntsec" on?

If not, adding "smbntsec" to your CYGWIN environment variable may be all
that's needed.  If you *do* have it set, does Windows show different owner
and permissions via pure Windows means (i.e., the "Advanced" security
properties in Windows Explorer)?

Basically, Cygwin can only do as much as the underlying Windows permits it
to.  If the underlying Windows doesn't recognize MVFS owner and
attributes, it's unlikely that Cygwin will.  If Windows does show the
correct permissions and Cygwin doesn't (and "ntsec/smbntsec" are both on),
it's probably a bug, and will have to be debugged/fixed (if it can't be
reproduced by the Cygwin developers, you'll need to help in debugging it
on your machine).
HTH,
