2.2 Ticket Management

On many systems, Kerberos is built into the login program, and you get tickets automatically when you log in. Other programs, such as rsh, rcp, telnet, and rlogin, can forward copies of your tickets to the remote host. Most of these programs also automatically destroy your tickets when they exit. However, MIT recommends that you explicitly destroy your Kerberos tickets when you are through with them, just to be sure. One way to help ensure that this happens is to add the kdestroy command to your .logout file. Additionally, if you are going to be away from your machine and are concerned about an intruder using your permissions, it is safest to either destroy all copies of your tickets, or use a screensaver that locks the screen.
