Each group that you define to RACF® must be owned by a RACF-defined user or by its superior group. You assign ownership of a group with the ADDGROUP command when you create a new group profile or with the ALTGROUP command when you change an existing group profile. If you are the owner of a group (or if you are a connected user who has the group-SPECIAL attribute), you have the authority to:

• Define new users to RACF (provided you also have the CLAUTH attribute for the USER class)
• Connect and remove users from the group
• Delegate and change group authorities and set the default UACC for all new resources belonging to members of the group
• Modify, list, and delete the group profile
• Define, delete, and list the names of the subgroups under the group
• Specify the group terminal option
