A snippet from Robert's presentation To help replace BPX.DEFAULT.USER, z/OS 1.11 introduced the FACILITY class profile BPX.UNIQUE.USER. Defining this newer profile causes RACF to automatically add OMVS segments and assign ids to users and groups that do not already have segments. RACF creates the segments when the user first accesses Unix (i.e., dubs). BPX.UNIQUE.USER works in combination with FACILITY class profile BPX.NEXT.USER, which defines the uid and gid number ranges to be used for automatic id assignment. Use of these profiles requires your databases to be in the Application Identity Mapping (AIM) structure.
