MyGroups

Administrator Guidelines

MyGroups are used to share information and resources in a collaborative environment. They are linked to the LDAP directory and can be created, used, and deleted as needed. Following are guidelines for naming, managing membership, and administering your MyGroups groups.

If you want to depend on using a MyGroups groupname in the UNIX/Linux environment, we recommend limiting the name of your group to eight (8) characters.

MyGroups Names

When you create a new group in MyGroups, you need to give it a unique, descriptive name. Once named, a MyGroups name cannot be changed. The following list is intended to serve as a guide for naming a new group.

A MyGroups name...

  1. Can be any name, as long as the name is not in use by another group.
  2. Must be at least 4 characters and no more than 22 characters.
  3. Must begin with a minimum of four alphabetic characters.
  4. Can include numbers after the first four characters.
  5. May include underscores (_) and hyphens (-).
  6. May not include spaces.
  7. Should be descriptive of its purpose and easy to remember. Please try to be sensitive to names that might be offensive to others.
  8. Should not be too generic. For example, a name similar to "Leadership" is not very descriptive or helpful to understanding the intended use of the group; instead, a name such as "StudentLeadership" might be a better choice.
  9. Cannot end with either -admin or -owner.
  10. Cannot be changed but can be reused immediately after an existing group with the same name is deleted.

If a concern is reported to postmaster@Virginia.edu about the name of a MyGroups group, the name will be reviewed and appropriate action will be taken to address the concern, if needed.

MyGroups Membership

MyGroups group membership is managed by the group administrator. Membership management guidelines specify that:

  1. Only MyGroups group administrators can add or remove individual members from a group.
  2. The creator of a MyGroups group need not be a member of the group.
  3. Membership in a MyGroups group is viewable only by the group members.
  4. At the present time, the number of members in a MyGroups group is unlimited.
  5. To add members of another MyGroups group to a new MyGroups group, the creator of the new group must be the administrator of the group(s) being added. Note: It is the members of the added group that populate the new group, not the existing MyGroups group name.
  6. MyGroups group administrators are responsible for removal of group members who leave the University.

MyGroups Management

Additional MyGroups group administration guidelines:

  1. MyGroups can have multiple administrators.
  2. MyGroups administrators must have an affiliation with the University of Virginia (faculty, staff, or student).
  3. MyGroups can be deleted by the group administrator.
  4. If a MyGroups group is accidentally deleted, it must be recreated by the group administrator. A deleted group cannot be restored from backup.
  5. If you are not the administrator of a MyGroups group, but need to be made a group administrator, contact the current administrator of the existing group to request the change. Be sure to specify the computing ID of the new adminstrator. If a group administrator is unresponsive to your request, contact postmaster@Virginia.edu with a description of the circumstances and request assistance. Include the name of the MyGroups group and the UVa email address(es) of the new administrator(s) for the MyGroups group in your request.

UNIX/Linux Limitations on MyGroups

There are important limitations with regard to MyGroups when using a UNIX/Linux host:

  1. The maximum number of groups that can be requested from the Network File System (NFS) is limited to 16.
    This means that if you are in more than sixteen MyGroups, you may not be able to request or use all of them on a UNIX/Linux platform. To view all of your MyGroups as UNIX groups, use the id command at the command line prompt on your host:
    hostname: /home/mst3k $ id -Gn mst3k

    where mst3k is a valid UVa computing ID. This will produce a list of all the names of your MyGroups available as UNIX groups:

    staff DirectoryGroupsCDP bis-pmsc SakaiDevelopers ldap-test tgisit spinners ba pubs isss genmgr webstuff accs it-myuva cap3fgrp emp-evp CCPcook enders collab-user SON-admin mygroups collab-participants-0
  2. There is an eight-character limit on group names by some UNIX commands.

    Certain UNIX commands, such as the groups command, will fail to produce results on group names that are longer than 8 characters. For example:

    hostname: /home/mst3k $ groups mst3k
    produces a list of only those groups with names that are 8 characters or less:
    mst3k : staff bis-pmsc tgisit spinners ba pubs isss genmgr webstuff accs it-myuva cap3fgrp emp-evp mygroups

    Other commands, such as the list command, ls -l, will truncate group names longer than 8 characters.

    If you want to depend on using a MyGroups groupname in the UNIX/Linux environment, we recommend limiting the name of your group to eight (8) characters.
