After getting the initial TGT, the client sends a request to TGS. The request contains the name of the server, the TGT received at Phase 1, and an authenticator to prove the client itself. The TGS will check the TGT and authenticator. If valid, the TGS grants a ticket to the client, and the ticket contains the client’s name, the server’s name, timestamp, and other information, along with a newly generated random session key to be used between the client and the server.
