Kerberos Ticket Auto renewal is commonly used in corporate environments as a mechanism behind Single Sign-On (SSO) which allows to use intranet resources without entering password every time.
Automatic Ticket Renewal - if a ticket expires (or disappears for any reason) the app will instantly get another one using the password saved in Keychain.
If you choose not to save any password for the ticket, the app will still use passwordless renewal (`kinit -R`) when possible, keeping the ticket actual until maximum renewable lifetime of the ticket runs out.
Changing Expired Password - displays notification when Kerberos password expires and allows to change it.
Multiple tickets can be maintained.
Can optionally prevent others apps from changing the default ticket.
