Yes, it is becoming well known that doing this look up, when the UID or GID is not unique, seems to always result in the wrong answer. Which makes me curious. And perhaps a solution. Very little work in z/OS runs without a ESM (like RACF) id and one or more active groups. So why doesn't the id

Thanks - great answer. It's basically what I suspected (or rather, feared). So for the supplementary question, what command _should_ be used to identify the current user, as known to RACF? -- For IBM-MAIN subscribe / signoff

If your RACF data base is at AIM 3 (strongly recommended), then RACF itself enforces a unique UID on RACF user ids and unique a GID on RACF group ids. But it will allow duplicates if the SHARED parameter is specified on the ADDUSER/ADDGROUP command. On Tue, Jun 18, 2013 at 9:15 AM, Paul Gilmartin
