Error description
Messages arriving over a cluster receiver channel are put to the dead letter queue with an MQRC 2035 as the USER ID used to check authorization is defaulting to the CHIN task authority instead of to the MCAUSER ID which was mapped by CHLAUTH rule. Change Team finds that the CHLAUTH rule is matched as pStatus.MCAUser is set based on the rule however, CD.MCAUserIdentifier is blank. This results in MQPUT being issued using the CHIN userid. The issue in rriCheckChlAuth is that MCAUserIdentifier is not updated in the status entry.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When using CHLAUTH QMGRMAP * * authentication records to set MCAUSERID * * to receiver channels, incoming * * messages are put to dead letter queue * * with MQRC 2035 MQRC_NOT_AUTHORIZED. * **************************************************************** * RECOMMENDATION: * **************************************************************** DISPLAY CHSTATUS shows that the correct MCA userID has been set to the channel but messages are discarded to dead letter queue. The channel definition control blocks have two fields to set the MCA userId: MCAUserID and MCAUserIdentifier. The CHLAUTH MCAUser is only copied to MCAUserID and MCAUserIdentifier is left blanks resulting in messages put to dead letter queue with MQRC 2035 MQRC_NOT_AUTHORIZED.
Problem conclusion
CMQXRMSA (rriCheckChlAuth) has been changed to copy MCAUser to MCAUserID and MCAUserIdentifier in the channel definition control blocks. 000Y CMQXRMSA
