A method and apparatus for associating session ticket includes a ticketing
authority server. The ticketing authority server receives a ticket
generation request and information about a client node. It identifies a
master session ticket associated in a storage element with the client
node. The ticketing authority server then generates a derivative session
ticket for the client node and associates the derivative session ticket
with the master session ticket. Finally, the ticketing authority server
stores information about the client node and the derivative session
ticket in the storage element.
