Following the steps in the post "https://mqgem.wordpress.com/2013/03/21/mq_chlauth_the_back_stop_rule/"I have created a "warning back-stop rule"
My 3 access attempts were recorded in the SYSTEM.ADMIN.CHANNEL.EVENT,
but none MQRC_CHANNEL_BLOCKED_WARNING event listed in that queue and the problem still remains..

And did you then work through the other posts? Specifically the one titled CHLAUTH - Allow some privileged admins?

Problem was related to the userID and not the CLAUTH.
After checking the User Identification Compatibilty mode connection was established and access problem fixed.

User identification compatibility Mode : When selected, the userid and password are passed to the server in a way compatible with security exits created prior to IBM MQ Version 8.0. (in our case MQ v7.5.0.2)

So is/was an exit being used?

It was the default value just in case. It being set just means the user hasn't changed it. Doesn't mean there were exits.
