Setting up Windows Server 2012 RADIUS and Sonicwall NSA – error “RADIUS communication error”

When trying to setup Windows server 2012 RADIUS server – NPS to work with Sonicwall NSA appliance you will receive and error “RADIUS communication error” when testing RADIUS settings in Sonicwall NSA appliance. Do not use the generated key from Server 2012 interface. It is too long for the Sonicwall management to accept it. I only used first 15 characters of the key and deleted the rest.
