### The clients Directory

This directory contains the code for several user-oriented programs.

kdestroy
  This program destroys the user's active Kerberos authorization tickets. MIT recommends that users `kdestroy` before logging out.
kinit
  This program prompts users for their Kerberos principal name and password, and attempts to get an initial ticket-granting-ticket for that principal.
klist
  This program lists the Kerberos principal and Kerberos tickets held in a credentials cache, or the keys held in a keytab file.
kpasswd
  This program changes a user's Kerberos password.
ksu
  This program is a Kerberized version of the `su` program that is meant to securely change the real and effective user ID to that of the target user and to create a new security context.
kvno
  This program acquires a service ticket for the specified Kerberos principals and prints out the key version numbers of each.
