> Authentication negotiation HTTP response should be automatically sent when needed when Kerberos authentication is enabled.  
> The expected HTTP response during authentication failure when Kerberos authentication into Ambari is enabled is as follows:
> {noformat}
> HTTP/1.1 401 Authentication requested
> WWW-Authenticate: Negotiate
> {noformat}
> When Kerberos authentication into Ambari is not enabled the expected HTTP response for an authentication failure is:
> {noformat}
> HTTP/1.1 403 Missing authentication token
> {noformat}
