Disabled `mfa-duo` if your CAS doesn't have MFA enabled #14

Since this project seems to be abundant, at least want to leave this here so help somebody if they come across this:

If you receive this error:

org.jasig.cas.client.validation.TicketValidationException: No principal was found in the response from the CAS server.

Try comment out the following line in web.xml

        <init-param>
            <param-name>authn_method</param-name>
            <param-value>mfa-duo</param-value>
        </init-param>

This happened because your CAS server does not support MFA authentication
