Do You Need to Worry About Tickets?

With SEAM installed, Kerberos is built into the login command, and you will get tickets automatically when you log in. The Kerberized commands rsh, rcp, telnet, and rlogin are usually set up to forward copies of your tickets to the other machines, so you don't have to ask explicitly for tickets to get access to those machines. (It's possible that your SEAM configuration does not include this automatic forwarding, but it is the default behavior.) See "Overview of Kerberized Commands" and "Forwarding Tickets with -f and -F" for more on forwarding tickets.

Most of the Kerberized commands also automatically destroy your tickets when they exit. However, you might want to explicitly destroy your Kerberos tickets with kdestroy when you are through with them, just to be sure. See "How to Destroy Tickets" for more information on kdestroy.
