kpasswdd(8)

NAME

     kpasswdd -- Kerberos 5 password changing server

SYNOPSIS

     kpasswdd [--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:

     --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.
