kdestroy(8krb)
Name
kdestroy − destroy Kerberos tickets
Syntax
/usr/bin/kdestroy [ −f ] [ −q ]
Description
The kdestroy utility destroys the user’s active Kerberos authorization tickets by writing zeros to the file that contains them. If the ticket file does not exist, kdestroy displays a message to that effect.
After overwriting the file, kdestroy removes the file from the system. The utility displays a message indicating the success or failure of the operation. If kdestroy is unable to destroy the ticket file, the utility will issue a warning by making the terminal beep. The ticket file has the name, /var/dss/kerberos/tkt/tkt[uid] where uid is the user ID of the kdestroy process.
If your site does not provide a ticket-destroying mechanism, you can place the kdestroy command in your .logout file so that your tickets are destroyed automatically at logout.
Options
−f Causes kdestroy to run without displaying the status message.
−q Disables terminal beeping if kdestroy fails to destroy the tickets.
Restrictions
The kdestroy utility is useful only in environments with user-level authentication. ULTRIX Kerberos does not support user-level authentication.
Only the tickets in the user’s current ticket file are destroyed.
Files
/var/dss/kerberos/tkt/tkt[uid]
