Hi NetBSD folks,

I'd like to know how can I use only the group names in /etc/ftpchroot to
restrict access by ftp only to the home directory of the users in NetBSD
1.41, I can see that if I use on FreeBSD 3.3 @ before the groupname in this
file  it works, but it doesn't work under NetBSD. I can do this using
WU-Ftpd in NetBSD too, but I dislike to use WU-Ftpd so someone can help me?
