KPASSWDD(8)               BSD 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 pro-cesses processes
     cesses requests when they arrive. It changes the database directly and should thus only run on the mas-ter master
     ter 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 termi-nated. terminated.
             nated.

     -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.
