6 kdestroy - destroy Kerberos tickets
7
9 kdestroy [-q] [-c cache_name]
10
12 The kdestroy utility destroys the user's active Kerberos authorization
13 tickets by writing zeros to the specified credentials cache that con‐
14 tains them. If the credentials cache is not specified, the default
15 credentials cache is destroyed.
16
18 -q Run quietly. Normally kdestroy beeps if it fails to destroy the
19 user's tickets. The -q flag suppresses this behavior.
20 -c cache_name
22 use cache_name as the credentials (ticket) cache name and loca‐
23 tion; if this option is not used, the default cache name and
24 location are used.
25 The default credentials cache may vary between systems. If the
27 KRB5CCNAME environment variable is set, its value is used to
28 name the default ticket cache.
29 Most installations recommend that you place the kdestroy command in
31 your .logout file, so that your tickets are destroyed automatically
32 when you log out.
33
35 Kdestroy uses the following environment variables:
36 KRB5CCNAME Location of the Kerberos 5 credentials (ticket) cache.
38
40 /tmp/krb5cc_[uid] default location of Kerberos 5 credentials cache
41 ([uid] is the decimal UID of the user).
42
44 kinit(1), klist(1), krb5(3)
45
47 Only the tickets in the specified credentials cache are destroyed.
48 Separate ticket caches are used to hold root instance and password
49 changing tickets. These should probably be destroyed too, or all of a
50 user's tickets kept in a single credentials cache.
