Looking at the output of /usr/bin/id -a was my first guess too. But
this fails quickly because the names are localized. Seriously MS runs
the Windows group names through the l10n wringer!! So what works on
Windows for Germany will surely fail for Windows for Japan. Thus I am
looking for a more portable solution.

Maybe the numeric group ids are more 'portable' across the Windows
versions for different countries?
