I have a MPE 18.104.22.168 system integrated with my CCM 22.214.171.12400-3 system. I have setup the AXL User authentication and users can log in to the web interface just fine. The issue I am having is that they cannot login through the phone when they call the system, it says their passwords are not recognized. Their password *should* be the PIN defined in CCM but that doesn't seem to be the case, I changed my PIN and tried logging in through the TUI with no luck. Any help would be appreciated.
Seems you are hitting a bug: CSCsk89314 VUI Authentication to Communications Manager 5.x Fails due to PWD Tag.
The CUCM version you are running does not include the fix, so you can contact TAC and ask for the ES you need.
Hope this helps!
