User IDs for resource security (MQOPEN, MQSUB, and MQPUT1)

This information shows the contents of the user IDs for normal and alternate user IDs for each type of connection. The number of checks is defined by the RESLEVEL profile. The user ID checked is that used for MQOPEN, MQSUB, or MQPUT1 calls.

Note: All user ID fields are checked exactly as they are received. No conversions take place, and, for example, three user ID fields containing Bob, BOB, and bob are not equivalent.
