A free implementation of this protocol is available from the Massachusetts Institute of Technology. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. Scenario: User (IE) => AppServer (Tomcat, under Linux) => Backend (webservice - REST service on Windows) Kerberos is a network authentication protocol. It's possible to get a service ticket for the client (remote user) in the server side in order to use that ticket to authenticate against another backend?
