An External Security Exit was configured for Web Viewer 12.1. Users could not log in when the External Security Exit was in place in the CAOMWV12_HOME"\config\ directory.
SECURITY=INTERNAL is required with OM View when using an External security Exit with Web Viewer 12.1
The External Security Exit itself was working.
With logging enabled, there was an error message from ACF2 blocking access. It was necessary to reconfigure OM View to use SECURITY=INTERNAL when using an External Security Exit with Web Viewer 12.1.
After setting OM View to use Internal Security, users were able to log on.
To turn on logging:
There is a configuration file called "SecurityExitUsers.properties" located in "CAOMWV12_HOME"\config\ directory.
In that file should be a property which should be set to true:
# Turn debug messages On/OFF
CONFIG.debug=true
The logs all go to System Out so they are located in the Tomcat log once the server starts up.
