My copy of the /etc/group man page says:
A user is automatically in a group if that group was speci-
fied in their /etc/passwd entry and does not need to be added to that
group in the /etc/group file.
I'm not sure how that corresponds with what you said. In any case,
there are two ways someone can get into a group: that group number can
be the one listed for that user in the group field of the
/etc/password file, *or* they can be listed as being in that group in
/etc/group. The page doesn't say anything about vipw; but using that
(or other tools) to change the group in /etc/passwd isn't going to
change things in /etc/group.
This happens at login time; if you change any of them, you have to get
a new login session to see the changes.
The manual page might need to be clearer, but I'm not sure how to do
that.
