MQSeries.net :: View topic - Security Exits and feedback from receiver to sender

I've been scratching my head on this for long enough, and I haven't found a reply by searching the forums, so I hope saomeone can provide some help.

The problem (short version): how do I pass information from the "receiver" security exit back to the sender security exit ?

A longer description:
The situation I am working in is that of a client machine attempting to open a connection with a server machine (I say client and server, but they are basically a sender and a receiver). The client side security exit passes to the server side security exit a bunch of info, and the security exit on the server side performs some authentication/authorization logic to verify that the client can actually send messages to/read messages from the server. The info passed from the client security exit to the server security exit, in fact, include user ID, password, and other such things.

Now, in some cases all goes fine and the server side security exit will return an MQXCC_OK code to indicate that all is well, and the connection should be opened.

In other cases, though, something goes wrong (say a bad password). In this case the server side security exit returns an MAXCC_CLOSE_CHANNEL code. I would like to pass a string back to the client side security exit (such as "Bad ID" or "Bad Password" or one of a few others), and I have tried (in the server side security exit) to stick this string in either the agent buffer or the exit buffer. I specify ExitResponse2 = MQXR2_USE_AGENT_BUFFER (or USE_EXIT_BUFFER) as well.
However, the next step in the chain of events seems to be the client side security exit being invoked with MQXR_TERM, and, when logging the agent buffer and/or the exit buffer in that exit I get a zero-length buffer.

Suggestions?
Alternatives?

Thanks in advance,
F.O.R.
