Explanation
You tried to assign a user a UID value that is
already in use, or you tried to assign a group a GID that is already
in use. The user or group is identified by name.
 Note that it is possible that more than one user or group is using
the value, but only one of them is identified, and that one is arbitrarily
chosen.  If you want to see a complete list, issue SEARCH CLASS(USER)
UID(id) or SEARCH CLASS(GROUP) GID(id).

System action
Command processing stops.

User response
Do one of the following tasks:Choose another value for id  and issue SEARCH
CLASS(USER) UID(id) or SEARCH CLASS(GROUP) GID(id)
 to make sure that the new value is not also in use.  Then, reissue
the original command with the new value for id.
Let RACF® choose an unused
value for you by reissuing the command with the AUTOUID or AUTOGID
keyword.  For example: ADDUSER JORDAN OMVS(AUTOUID)
Reissue the command with the SHARED keyword to force RACF to assign the id despite
it already being in use.  The SHARED keyword requires the SPECIAL
attribute or READ authority to the SHARED.IDS resource in the UNIXPRIV
class.

RACF Security
Administrator Response
 If the command issuer should be
allowed to assign shared UIDs and GIDs, then permit the user with
READ access to the resource named SHARED.IDS in the UNIXPRIV class.
The user should then reissue the command using the SHARED keyword.
