KPASSWDD(8) BSD System Manager's Manual KPASSWDD(8)
kpasswdd -- Kerberos 5 password changing server
kpasswdd [--check-library=library] [--check-function=function] [-k kspec
| --keytab=kspec] [-r realm | --realm=realm] [-p string |
--port=string] [--version] [--help]
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.
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, 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
-p string, --port=string
Port to listen on (default service kpasswd - 464).
If an error occurs, the error message is returned to the user and/or
logged to syslog.
The default password quality checks are too basic.
