I am writing a client application that connects to a remote queue manager which uses a Channel Security Exit to do user/pwd authentication. My client app is currently written in C++ and I am trying to avoid doing a complete re-write to port it to C.
From the description I was given of the Security Exit, I know that I need to do the equivalent of filling in the CSPUserIdPtr and CSPPasswordPtr fields of the MQCSP Security Parameters structure in the MQCNO connection options struct of MQCONNX.
The C++ API has setUserID and setPassword methods for both ImqQueueManager and ImqChannel classes. Which of these is appropriate to call in order to fill in the MQCSP struct? I assume that I also need to call ImqQueueManager::setAuthenticationType(MQCSP_AUTH_USER_ID_AND_PWD) .
Also, how can I set the MQCNO.Version field to MQCNO_VERSION_5 in C++ in order for the MQCSP to be recognized? When I was experimenting with the client code, I turned on tracing in the Queue Manager (strmqtrc -e -t all) but I was never able to see any effect in the hex display of the Connect Options struct of the MQCONN call - and I never could figure out how to get tracing to display the fields for MQCONNX. Is that even possible?
Thanks very much for any insight.
P.S. I am runing MQ v6.0.2.4 on AIX and Linux |

I was able to answer some of my questions (but not all) with a little more digging through the docs. I learned from the MQI Cross Reference tables in the Using C++ guide that the ImqQueueManager attributes for authentication type, user id and password correspond to MQCSP. While the user id and password attributes of the ImqChannel class correspond to the MQCD struct, which is not what I want.
OK, so now I know that I definitely want to call:
ImqQueuemanager::setAuthenticationType()
ImqQueuemanager::seUserId()
and ImqQueuemanager::setPassword()
But how can I make sure that the MQCNO.Version field is set correctly? Will that just happen automatically?
Also, is it possible to set tracing (strmqtrc) so that it displays these values in the Queue Manager? |

Is the server-side security exit expecting both the UserId and Password in plain text or are you supposed to encrypt one or both fields?
How do you tell the server-side which resource (server name or LDAP server) you want the UserId and Password to be authenticated against?

The IMQ class will set it.
