In v7 and any of its derivatives (perhaps all), login does not
look at /etc/group.  Your group number is set in your /etc/passwd
entry.  /etc/group is used: (a) to assign a name to that group
for purposes of ls -lg and similar needs; and (b) to permit
newgrp and similar mechanisms for changing your "current" group.
(Yes, I know 4.xBSD does this part differently.)

We have lots of users whose login names don't appear in their
group files.
