ktd[elete] -p principal_name -v version_number [-f keyfile]

 Deletes a sever or machine principal's password entry from a keytab
 file.

 The -p option specifies the name of the server or machine principal
 for whom you are deleting a password entry.

 The -v option specifies the version number of the password you want
 to delete.  Version numbers are assigned to a principal's password
 whenever the principal's password is changed.  This allows any
 servers or machines still using tickets granted under the old pass-
 word to run without interruption until the ticket expires naturally.

 The -f option specifies the name of the server keytab file on the
 local node from which you want to delete passwords. If you do not
 specify a keytab file name, dce$local:[krb5]v5srvtab.; is used.
 Note that you must be privileged to delete entries in the default
 keytab file.  You must have the appropriate access rights to
 delete entries in other keytab files.
