NAME
kdestroy - destroy Kerberos ticketsSYNOPSIS
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.OPTIONS
- -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.
FILES
- /tmp/krb5cc_[uid]
- default location of Kerberos 5 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.
