KPASSWDD(8)		     System Manager's Manual		     KPASSWDD(8)

NAME
     kpasswdd -- Kerberos 5 password changing server

SYNOPSIS
     kpasswdd [--addresses=address] [--check-library=library]
	      [--check-function=function] [-k kspec | --keytab=kspec] [-r realm
	      | --realm=realm] [-p string | --port=string] [--version] [--help]

DESCRIPTION
     kpasswdd  serves  request	for password changes. It listens on UDP port 464
     (service kpasswd) and processes requests when they arrive. It  changes  the
     database directly and should thus only run on the master KDC.

     Supported options:

     --addresses=address
	     For each till the argument is given, add the address to what kpass-
	     wdd should listen too.

     --check-library=library
	     If your system has support for dynamic loading of shared libraries,
	     you  can  use  an external function to check password quality. This
	     option specifies which library to load.

     --check-function=function
	     This is the function to call in the loaded  library.  The	function
	     should look like this:

	     const  char  *  passwd_check(krb5_context	context,  krb5_principal
	     principal, krb5_data *password)

	     context is an initialized context; principal is the one  who  tries
	     to  change  passwords,  and password is the new password. Note that
	     the password (in password->data) is not zero terminated.

     -k kspec, --keytab=kspec
	     Keytab to get authentication key from.

     -r realm, --realm=realm
	     Default realm.

     -p string, --port=string
	     Port to listen on (default service kpasswd - 464).

DIAGNOSTICS
     If an error occurs, the error message is returned to the user and/or logged
     to syslog.

BUGS
     The default password quality checks are too basic.
