You can only have one primary group which is the group that
is your default group for file creation.
`newgrp' isn't supported yet but maybe later (shouldn't be too
complex).

This isn't completely right! A group may be used as owner of an
object but a user must not be used as "group" in a security
descriptor. So users shouldn't reside in the group file though
they wouldn't disturb there.

Grin! The 't' bit is the sticky bit that is used in a linux style
manner. It only make sense for directories and it's typically set
on /tmp (rwxrwxrwt) and has the effect, that anybody may read and
write in /tmp but he/she can't erase files of other users.
Unfortunately, the sticky bit is set in ntsec by mistake. I had
corrected this a few days ago and the _next_ snapshot after yours
(19991001) behaves correctly.
