It is. The shadow password package does not support BSD suplemental groups -
you have one active group at a time. You start off being in the group
specified in your /etc/passwd entry, but can chgrp to anything in /etc/group.
Either fix the sources to the shadow password package, or use the poeigl
package that has a BSD-suplemental group supporting login.
If I were you, and were concerned about security, I'd switch back to
a normal password file, install npasswd (Using something like /usr/dict/words
as the dictionary), and run crack on the pasword file to catch current
users with crackable passwords.
