Changing group name, changes the image for the group

There are two parts to users and groups in Integrity:

Within the "Workflows and Documents" node in the admin client, you are dealing with database records for users and groups stored in the Integrity database. These records are linked to items within the database (i.e. the 'Created By' field of an item would point to one of these user records).

The database records themselves, however, do not store passwords (for users) or group membership (for groups); that information comes from the backing authentication realm (e.g. MKS Domain or LDAP/AD).

You may go into the Workflows and Documents node in the admin client and manually create a user or group, however the user won't be able to login and the group won't have any members unless there is a corresponding user/group in your authentication realm.

The icon you are referring to indicates whether or not the user/group is "in realm" (backed in the LDAP server). If you manually edited the group name under W&D, this does not change the corresponding group in LDAP, and therefore the icon shows the group is no longer in realm (looks like a deactivated icon). If this is the case, you will need to update the corresponding group in MKS Domain/LDAP/AD or create a new one. If that was already done, or once you have done so, the cache of users/groups on the server will need to be updated. This happens automatically, but you can force a refresh by right-clicking on the W&D node in the admin client and choosing "Refresh user/group cache".
