NAME
       unix_chkpwd - check the password of the invoking user

SYNOPSIS
       <not invoked manually>

DESCRIPTION
       A  helper  binary for the pam_unix module, unix_chkpwd, is
       provided to check the user's password when it is stored in
       a  read  protected  database,  such as shadow'd passwords.
       This binary is very simple and will only check  the  pass-
       word  of  the user invoking it. It is called transparently
       on behalf of the user by the authenticating  component  of
       the pam_unix module. In this way it is possible for appli-
       cations like xlock to work work without being setuid root.

USAGE
       This  program  is  not  intended  to be called directly by
       users and will log to syslog if it  is  called  imporperly
       (i.e., by some one trying exploit it).
