commit b562400826409deceb0d52ffbe6570670ee9db55

    Don't check kpasswd reply address
    
    Don't check the address of the kpasswd server when parsing the reply
    we received from it.  If the server's address was modified by a proxy
    or other network element, the user will be incorrectly warned that the
    password change failed when it succeeded.  The check is unnecessary as
    the kpasswd protocol is not subject to a reflection attack.
