unix_chkpwd - check the password of the invoking user
<not invoked manually>
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 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.
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).
