KDESTROY(1) User Commands KDESTROY(1)

NAME

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(7) for syntax and details.

FILES

/tmp/krb5cc_uid
Default credentials cache (uid is the decimal UID of
the user).

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 files should probably be destroyed too, or all
of a user's tickets should be kept in a single credential cache.
