After upgrading z/OS to 2.5, the following message is received when signing on to z/OS System Display and Search Facility (SDSF):
ISF024I USER xxxxx NOT AUTHORIZED TO SDSF, NO GROUP ASSIGNMENT
The External Security Manager (ESM) is Top Secret.
The ISFPARMs Conversion Utility will not convert the GROUP definitions, so it needs to be added to the Top Secret acid or PROFILE manually:
TSS ADD(owningacid) SDSF(GROUP)
TSS PER(user_acid or profile_acid) SDSF(GROUP) ACC(ALL)
