MarsNWE - group settings?

Hi all!

I hope that someone here has some experience with the MarsNWE netware
emulation. ;)

How can I force MarsNEW to write files with a specific group as owner?
The clients that do connect, use their usernames for writing the data,
but the data is written with group "root" not with group "users" as it
should be. I can´t find something about this in the docs. :/

Someone´s got a hint?!

Thanks and see ya...
Olly.
