This section describes the security arrangements for intra-group queuing.
Queue manager attributes IGQAUT (IGQ authority) and IGQUSER (IGQ agent user ID) can be set to control the level of security checking that is performed when the IGQ agent opens destination queues.
The IGQAUT attribute can be set to indicate the type of security checks to be performed, and hence to determine the userids to be used by the IGQ agent when it establishes the authority to put messages on to the destination queue.
The IGQAUT attribute is analogous to the PUTAUT attribute that is available on channel definitions.
The IGQUSER attribute can be used to nominate a user ID to be used by the IGQ agent when it establishes the authority to put messages on to a destination queue.
The IGQUSER attribute is analogous to the MCAUSER attribute that is available on channel definitions.
Refer to WebSphere MQ Script (MQSC) Command Reference and WebSphere MQ Application Programming Reference for more information about the IGQAUT and IGQUSER queue manager attributes. Refer to the chapter on security in WebSphere MQ for z/OS System Setup Guide for a table of the userids checked for intra-group queuing.
