User names for channels
When using channels between queue managers (server connects or client connects) a valid principal name must be established during connect processing.
The final principal name is created by IBM® MQ based on configuration options for channels (attribute MCAUSER) and/or the CHLAUTH rules (attributes CLNTUSER and MCAUSER).
The final principal name is validated against the principal database and must be found in order
to get a connection established. If the principal maps to a NonStop user outside the
MQM group, the following rules must be met in addition:
- + connect authority for the queue manager
- +get +put (and so on) for any entities like queues
