Passwords in groups were checked by newgrp, which changed the primary
effective and real group of a new forked shell to be the group specified
on the command line.
NetBSD does not ship with a newgrp command, although older versions of BSD,
and FreeBSD include a copy of newgrp. You should be able to use the FreeBSD
version of newgrp on NetBSD. Eventually we should put it back too since it
is part of the SUS (although not particularly useful).
