You cannot modify a distributed identity filter. If you need to make changes to a filter, delete it and define a new one.

Performance consideration: When you issue the RACMAP DELMAP command specifying both filter label and a user ID for which no user profile exists, RACF® searches all profiles in the IDIDMAP class to locate and delete all matching filters. This search might take an extended period of time.

For information about locating residual filters (filters that map to a user ID that no longer exists), see IRRRID00 considerations for distributed identity filters.
