NAME    [Toc]    [Back]

     kpasswdd - Kerberos 5 password changing server

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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

     Supported options:

             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.

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

             const  char  *  passwd_check(krb5_context   context,
             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    [Toc]    [Back]

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

BUGS    [Toc]    [Back]

     The default password quality checks are too basic.
