NAME
       unix_chkpwd - check the password of the invoking user

SYNOPSIS
       

DESCRIPTION
       A  helper  binary  for the pam_unix module, unix_chkpwd, is provided to
       check the users password  when  it  is  stored  in  a  read  protected
       database,  such	as  shadowd passwords. This binary is very simple and
       will only check the password 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  applications  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 improperly (i.e., by  someone  trying  to
       exploit it).
