You manage application user identities, such as Lotus Notes for z/OS short names and Novell Directory Services for OS/390 (NDS) user names, by administering user profiles. Through the ADDUSER, ALTUSER, and DELUSER commands, you can associate a RACF® user ID with an application user identity, and you can change and remove that association.

Each RACF user ID can map to both a Lotus® short name and an NDS user name, but no user ID can map to more than one Lotus short name or more than one NDS user name. In addition, each Lotus short name can map to only one user ID. Similarly, each NDS user name can map to only one user ID.

The application user identities that you specify in the identity segments of the user profiles must match the user identities defined by the administrators of each application. For example, the SNAME that you define for a RACF user ID must be the same short name that is defined for that user by the administrator of the Lotus Notes for z/OS application. For special considerations when selecting application user identities, see Considerations for application user names.
