 Well, gpasswd uses /etc/gshadow, what else?

 I'm talking about group paswords. I don't see a problem to support
 newgrp(1) as a way how to switch groups, but the question is if we
 really need to support the passwords.

 BTW, posix:

   There is no convenient way to enter a password into the group
   database. Use of group passwords is not encouraged, because by their
   very nature they encourage poor security practices. Group passwords
   may disappear in the future.
