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 kpasswdd 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.
