old parameters, defensive ... yes

Yes, thanks.

I maybe messed up something myself.

Right now when I run "chgrp -R 10513 somefolder" it gets shown as

drwxrwx---+   4 administrator dom�nen-benutzer  4096 Nov 21 12:14 somefolder

which is good.

(I dislike the fact that the german "domänen-benutzer" has an Umlaut in
it ... problematic with some commands)

I run some larger chgrp-command now to get these folders accessible again.

# getent group | grep -i utzer

does show nothing, though, I always forget if that has worked or not,
and why ...
