The time for a ticket is set by the KDC and is based upon the current time unless the client has requested a different start time. Clients do not have to request a start time, but they do include the time they want the ticket to expire. The KDC consults the Kerberos realm policy and adds the time indicated in the policy to the start time. If the client has requested a specific end time, the KDC adds the requested end time to the start time. Whichever time is shorter, the time calculated using the Kerberos policy or the time calculated using the client requested time, is the time used for the end time. If a client sends an expired session ticket to a server, then the server rejects it. It is then up to the client to go back to the KDC and request a new session ticket. However, if the client is already communicating with the server and the session ticket expires, communication continues to take place. Session tickets are used to authenticate the connection to the server. After the authentication has taken place, the session ticket can expire, but the connection will not be dropped. Ticket-granting tickets also expire on the basis of the time set in the Kerberos realm policy. If a client attempts to use an expired TGT with the KDC, then the KDC rejects it. At that point the client must request a new TGT from the KDC, using the user’s long-term key. It is possible to renew tickets as well as flag settings The Kerberos realm policy dictates whether tickets are renewable or not. If the policy allows tickets to be renewed, then the renewable flag is set in every ticket issued by the KDC. In this situation, the KDC places a time in the end time field and another time in the renew till time field of tickets. The time set in the renew till time field is equivalent to the time set in the start time field added to the maximum cumulative ticket life set in the Kerberos realm policy. The client must submit the ticket to the KDC prior to the original expiration time shown in the end time field. Every time the client sends a ticket back to the KDC, it must send a new authenticator also. When the KDC receives the ticket from the client, it checks the time set in the renew till time field. If the time has not already passed, then the KDC creates a new copy of the ticket that has a new time set in the end time field as well as a new session key. By issuing a new session key, the KDC helps to alleviate the possibility of compromised keys. 01 - 02 - 03 - 04 - 05 - 06 - 07 - 08 - 09 - 10 - 11 - 12 - 13 - 14 - 15 - 16 - 17 - 18 - 19 - 20 - |
