Ticket Granting Server (TGS)

• A TGS issues tickets to users who have been authenticated to the AS

• User first requests a ticket granting ticket, Tickettgs, from the AS and saves it in the client’s workstation

• A client requesting services applies to the TGS using the ticket to authenticate itself

• TGS then grants a ticket, TicketV, for the particular service

• Client saves this and uses it each time a service is requested
