The new group will then automatically inherit the expiration date and ownership list of the master group. You are teaching a class where students work as teams on individual projects. Each team is in a separate Unix group to restrict file access across teams. However you, as the instructor, need to see the work of all teams. Only this time it is the first week of the quarter and you are trying to organize the class teams.
Students change teams, new students sign up, others drop out.
All of which would normally necessitate e-mail exchanges with administrators. Using the new software you add or remove team group members directly. Obviously, this functionality extends to groups used for research projects. You need to become a member of a new group. But the new mem- bership will put you over the maximum group limit.
