Destroy Ticket | Destroy all existing tickets. This button is greyed out and not accessible if the Automatically Import option is selected and you have Windows domain tickets imported from your Windows Logon session.

Kerberos would immediately import them again. How to destroy tickets
Export Ticket | Export tickets to use in your Windows Logon session to a Windows domain. | Click this button to export a ticket you've obtained with the Get Ticket window into your Windows Logon Session.
