If the user ID associated with an identity mapping profile does not exist, delete the identity mapping profile.

• If the application user name contains only uppercase characters, use the RDELETE command to delete the profile.
• If the application user name contains lowercase characters, you cannot use the RDELETE command to delete the profile. One way to delete the profile is to create a dummy user ID with an LNOTES or NDS segment specifying the application user name for the identity mapping profile you want to delete. Then delete the dummy user ID. Another way to delete the profile is to modify the RACF® database using the BLKUPD command. For information on BLKUPD, see z/OS Security Server RACF Diagnosis Guide.
