The OMVS segment in group profiles

You can use the OMVS segment of the group profile to specify information about the group's z/OS UNIX group. Specifically, when you define a new z/OS UNIX group or change z/OS UNIX attributes for an existing group, you can specify the following information in the group's profile:

GID: The group's z/OS UNIX group identifier

To define or change information in the OMVS segment of a group profile, you must have the SPECIAL attribute or at least UPDATE authority to the segment through field-level access control.

To display information in the OMVS segment of a group profile, you must have the SPECIAL attribute or at least READ authority to the segment through field-level access control.

You can authorize users to access to the OMVS segment of a group profile using the GROUP.OMVS.* or the GROUP.OMVS.GID profile in the FIELD class.

When a GID is assigned to a group, all users connected to this group as their default group who have an z/OS UNIX user identifier (UID) in their user profile can use z/OS UNIX functions and can access z/OS UNIX files based on the GID and UID values assigned. If a user's current connect group is not their default group, a GID must also be assigned to the current connect group.
