I explained that in my mail and I already wrote
http://cygwin.com/cygwin-ug-net/ntsec.html at one point.  There are also
links on the MSDN web site which explain how it works.  The group concept
in Windows isn't much different from the group concept in Unix, except
that Windows applications don't really care for the owning group of
objects, typically.

We're striving for similarity...

I don't know about you, but on my Linux box I get something like this:

  $ id
  uid=500(corinna) gid=11125(vinschen) groups=11125(vinschen),33(tape),
  100(users),107(qemu),486(wireshark),1000(cvs),11126(libvirt)

Most of the time I don't care about the supplementary groups after my
primary group either, but that doesn't mean I don't want id to print
them, nor are they unimportant.
