NETC-56 Authentication type causes Lightswitch 2013 not to authenticate

We fixed this issue by creating a custom configuration field that allows user the user to override the default "Jasig CAS" authentication type string value.
Microsoft LightSwitch 2013 (Visual Studio 2013) requires the authentication type of the principal be "Forms" instead of "Jasig CAS"

Configuration in Web.config 
<casClientConfig authenticationType="Forms" />
