Resolution

 Review required system security changes in relation to OMVS segments.

Starting with z/OS 2.1, IBM has eliminated the security calls related to BPX.DEFAULT.USER. In doing so, IBM is enforcing the requirement that all Unix Systems Services (USS) work requires the userid (ACID) to have established USS credentials. This includes a unique UID, assigned default group and Home.

See Knowledge Document: Preparation for removal of Default OMVSUSR and OMVSGRP (CA-Top Secret for z/OS).
See Knowledge Document: Prepare upgrade to z/OS 2.1 and above with ACF2 r16 to remove BPX.DEFAULT.USER (CA-ACF2 for z/OS).
