We have a client that connects to our server. He has NO variable defined for a user_id. With just that, he cannot connect - no problem
IF I add an id to the svrconn channel MCA_user_ID his connection picks up whatever I write in there and uses it.. I must stress he does not define any user ID on his side.
When I look in the message header of the messages he sends, I see the user identifier is whatever I have defined in the channel user_ID
What is going on? |

The MCA_USER_IDENTIFIER of the channel supercedes any value that may be passed along by the client. Use this function carefully!!!

| The problem though is his code picks up the ID specified in OUR SVRCONN channel. How is this possible? |

| ... because that is the semantics of explcitly defining an MCA Userid ... if you specify a userid here then NO MATTER WHAT userid the client application supplies (or doesn't supply), authorization will be based on the MCA Userid. |

by the way, if you have a security exit running, THAT trumps all. The order for user id is...
It uses the user id that started the MCA process,
unless
the client flows a user id, then it uses that,
unless
the MCA_USER_IDENTIFIER is set, in which case that is used
unless
a security exit overides the MCA_USER_IDENTIFIER field and/or the flowed User ID.
