There is no way, because windows has no concept of "group of a file",
this is an old legacy unix/posix concept (what a mistake ...).

In windows you just have the owner and then anything else.

The owner can be any SID in theory, even a group, or even Everyone.

The ACLs in Windows do not require to list owner/group/other, it may be
just one entry, the owner, or any number including
users,groups,machines,other special SIDs.

This is a fundamental difference between the Identity model of Windows
and the Identity model we have in Linux. And unfortunately, while
Windows can "emulate" our identity model for Posix compatibility we
can't "emulate" easily the Windows model, esp when you have an Owner
that is not a user or you miss a group entry in the ACL.

Simo.
