Description of problem: Negotiation will not fallback to FORM authentication if the client has a kerberos token from a different KDC than what JBoss is configured to use. This results in the user getting presented with a 401 error and no way to login. Steps to Reproduce: Get a token from a different KDC than what JBoss is configured to use. Hit a Negotiation protected endpoint. This will result in a 401. With the patch applied, it is possible to fallback to form authentication.
