The requester sends the TGS this facts and Forwards the encrypted key to the server to gain the preferred provider. If all actions are dealt with effectively, the server accepts the ticket and plays the desired consumer carrier, which have to decrypt the important thing, affirm the Timestamp and Make contact with the Distribution middle to reap session keys.
