kdestroy - destroy Kerberos tickets SYNOPSIS
kdestroy [-5] [-4] [-q] [-c cache_name] DESCRIPTION
The kdestroy utility destroys the user's active Kerberos authorization tickets by writing zeros to the specified credentials cache that contains them. If the credentials cache is not specified, the default credentials cache is destroyed. If kdestroy was built with Kerberos 4 support, the default behavior is to destroy both Kerberos 5 and Kerberos 4 credentials. Otherwise, kdestroy will default to destroying only Kerberos 5 credentials. OPTIONS
-5 destroy Kerberos 5 credentials. This overrides whatever the default built-in behavior may be. This option may be used with -4 -4 destroy Kerberos 4 credentials. This overrides whatever the default built-in behavior may be. This option is only available if kinit was built with Kerberos 4 compatibility. This option may be used with -5 -q Run quietly. Normally kdestroy beeps if it fails to destroy the user's tickets. The -q flag suppresses this behavior. -c cache_name use cache_name as the credentials (ticket) cache name and location; if this option is not used, the default cache name and location are used. The default credentials cache may vary between systems. If the KRB5CCNAME environment variable is set, its value is used to name the default ticket cache. Most installations recommend that you place the kdestroy command in your .logout file, so that your tickets are destroyed automatically when you log out. ENVIRONMENT
Kdestroy uses the following environment variables: KRB5CCNAME Location of the Kerberos 5 credentials (ticket) cache. KRBTKFILE Filename of the Kerberos 4 credentials (ticket) cache. FILES
/tmp/krb5cc_[uid] default location of Kerberos 5 credentials cache ([uid] is the decimal UID of the user). /tmp/tkt[uid] default location of Kerberos 4 credentials cache ([uid] is the decimal UID of the user). SEE ALSO
kinit(1), klist(1), krb5(3) BUGS
Only the tickets in the specified credentials cache are destroyed. Separate ticket caches are used to hold root instance and password changing tickets. These should probably be destroyed too, or all of a user's tickets kept in a single credentials cache. KDESTROY(1)

kdestroy - destroy Kerberos tickets SYNOPSIS
/usr/bin/kdestroy [-q] [-c cache_name] DESCRIPTION
The kdestroy utility destroys the user's active Kerberos authorization tickets by writing zeros to the specified credentials cache that contains them. If the credentials cache is not specified, the default credentials cache is destroyed. If the credentials cache does not exist, kdestroy displays a message to that effect. After overwriting the cache, kdestroy removes the cache from the system. The utility displays a message indicating the success or failure of the operation. If kdestroy is unable to destroy the cache, it will warn you by making your terminal beep. If desired, you can place the kdestroy command in your .logout file so that your tickets are destroyed automatically when you logout. OPTIONS
The following options are supported: -c cache_name Uses cache_name as the credentials (ticket) cache name and location. If this option is not used, the default cache name and location are used. -q Runs quietly. Your terminal will not beep when kdestroy fails to destroy the tickets. ENVIRONMENT VARIABLES
kdestroy uses the following environment variable: KRB5CCNAME Location of the credentials (ticket) cache. See krb5envvar(5) for syntax and details. FILES
/tmp/krb5cc_uid Default credentials cache (uid is the decimal UID of the user). ATTRIBUTES
