> Users should be able to authenticate to use Ambari by providing a Kerberos token using SPNEGO - Simple and Protected GSSAPI Negotiation Mechanism.  This includes access to the Ambari REST API as well as the Ambari web-based UI. 
> The implementation should support the ability to perform the full SPNEGO handshake as well as access requests directly providing the appropriate HTTP header containing the Kerberos token. For example:
> {noformat}
> Authorization: Negotiate YIICcgY...r/vJcLO
> {noformat}
> In the full handshake model
> # The client requests access to a web resource
> # The server responds with an HTTP 401 status ({{Unauthorized}}), including the header {{WWW-Authenticate: Negotiate}}
> # The client generates the Kerberos data and creates a new request containing the authentication header - {{Authorization: Negotiate YIICcgY...r/vJcLO}}
> Since Ambari needs to generally return a HTTP status of 403 ({{Forbidden}}) when authentication is needed, a _hint_ must be sent along with the request indicate to Ambari that Kerberos authentication is desired.  If this _hint_ is received, then Ambari will respond with the appropriate status and header to initiate SPNEGO with the client. This _hint_ is an Ambari-specific header named "X-Negotiate-Authentication" with the value of "true":
> {noformat}
> X-Negotiate-Authentication: true
> {noformat}
> No matter what the handshake mechanism is (or lack of), once the Kerberos token is received by Ambari, Ambari is to parse and validate the token.  If a failure occurs, Ambari is to respond with the appropriate HTTP status and related header(s).  Upon success, the user's principal name is retrieved and converted into a _local_ user name.  The use of an auth-to-local rule set processor may be needed to perform this translation.  Using this _local_ username, an appropriate Ambari user account is located and used as the authenticated users identity - details, privileges, etc.... Failure to find an appropriate Ambari user account is to result in an authentication failure response.
