Once the Kerberos software has been installed on your Macintosh computer, you can customize the settings by clicking on Kerberos, then Preferences. Note that the Kerberos application is usually found in the Applications->Utilities folder. Settings you can customize include:
- The length of time a ticket stays open, under the Time Ranges tab.
- Getting tickets that can be forwarded to another machine, under the Default Ticket Options tab.
- Getting tickets without IP addresses (NAT mode), under the Default Ticket Options tab.
- Getting tickets that can be renewed for a certain number of days, under the Default Ticket Options tab.
On a single user computer, we recommend you leave these options at their default settings.
On a shared computer (such as one in a lab or public cluster), we recommend you shorten the lifetime of the ticket. That way, if you forget to clear your ticket, it won't remain open for several hours.
