Abstract
Abstract A method for authenticating an authorized user to multiple computer servers within a distributed computing environment after a single network sign-on is disclosed. In accordance with the method and system of the present invention, an authentication broker is provided within the distributed computing network. The authentication broker first receives an authentication request from a workstation. After a determination that the authentication request is valid, the authentication broker then issues a Kerberos Ticket Granting Ticket to the workstation. At this point, if there is a request by the workstation for accessing a Kerberos Ticket-based server within the distributed computing network, the authentication broker will issue a Kerberos Service Ticket to the workstation. Similarly, if there is a request by the workstation for accessing a passticket-based server within the distributed computing network, the authentication broker will issue a passticket to the workstation. Finally, if there is a request by the workstation for accessing a password-based server within the distributed computing network, the authentication broker will issue a password to the workstation. By this, accesses to all of the above servers within the distributed computing network can be granted via a single network authentication request.
