Overview#Ticket Granting Service as used within the Kerberos Protocol. We have also seen this referred to as a Ticket Granting Server.
The ticket-granting service request/response exchange is the Kerberos service ticket request and reply messages that are sent to the KDC from the client when it is instructed to obtain a Service Ticket for a server.
The TGS is the service that delivers Service Tickets for all the managed services to the Clients.
Each request sent to the TGS must be encrypted using the TGS Session Key.
