Hi  Felix!

Thanks that you have time for Torque even on your vacation.

Cygwin often uses group 'None' (513) or group 'Domain Users' (10513).
This is its some specificity.
But Torque works nevertheless.

You can use the 'id' Cygwin's command for more detailed information 
about users and groups. For example:

Administrator at vxp64 ~
$ id
uid=500(Administrator) gid=513(None) groups=513(None),544(Administrators),545(Users)

user at vxp64 ~
$ id
uid=1003(user) gid=513(None) groups=513(None),545(Users)

For Cygwin 1.7 in Torque-2.5-beta this problem is solved already,
and so  I am surprised that you mention it.

Check your version.
Was it rewritten?

It is very interesting for our team.

Especially Server 2003 x64 and Server 2008 x64 which haven't been tested
