users not belonging to the "users" group

["C. Gatzemeier" <c.gatzemeier@tu-bs.de>]

There is another issue related to getting user collaboration working
out of the box:

Users do not belong to the "users" group, thus creating
say /home/group/users as a (sgid) group directory to provide a way for
the users of a system to collaborate on something does not work.

Either adduser would have to add all new (and existing) users
explicitly to the users group and fill /etc/group with all user names,
or pam_group can dynamically add users to the users group when they
login.

Following the pam_group line for /etc/security/group.conf:
*; *; *; Al0000-2400; users

Any preferences?

Cheers,
