You can delete a group if you are the group’s owner, a superuser, a member of the group that owns the group to be deleted, or identified in the group’s group_admin attribute, either as an individual or as a member of a group specified in the attribute. However, to preserve repository consistency, do not remove groups from the repository. Instead, remove all members of the group and leave the group in the repository, or reassign all objects owned by the group to another group or user and then delete the group.
To delete a group:
Navigate to Administration > User Management > Groups to access the Groups page.
Select the name of the group you are deleting and then select File > Delete.
Click OK to confirm that you want to delete the group.
