This is one of those problems between your seat and the keyboard, or to 
to put it another way, you. ;-)

You do not do it that way any more, in fact, as this is a DC and if the 
libnss-winbind links are set up, running:

getent group 'Unix System Users'

should produce output.

The next question has to be, why do you want/need to do this ?
