"Secret key mismatched" error occurs testing external RADIUS integration
========================================================================

Symptom
---------

``secret key mismatched`` error occurs when testing an integration of Genian
NAC with an external RADIUS (Windows) server, using the built in test feature
in the Web Console. 

Cause
-----

If the Genian NAC Policy Server requests authentication with an
unencrypted(PAP) method, but the RADIUS server does not allow non-encrypted
authentication requests, the authentication is rejected and the authentication
test window displays this error message.

Resolution
----------

Enable the RADIUS server to accept unencrypted authentication requests
