How can I associate a UID to a specific username on IBM z/OS Unix System Services? Within USS, I see content created in my user space which I do not own. File ownership lists a three digit numerical value, rather than a userid, which I presume to be a UID. I've unsuccessfully attempted to make a username association using commands: tsocmd "search class(USER) uid(###)" tsocmd "rlist unixmap u### all"
