    <title>DESCRIPTION</title>

    <para>
      <emphasis>unix_update</emphasis> is a helper program for the
      <emphasis>pam_unix</emphasis> module that updates the
      password of a given user. It is not intended to be run directly
      from the command line and logs a security violation if done so.
    </para>

    <para>
      The purpose of the helper is to enable tighter confinement of
      login and password changing services. The helper is thus called only
      when SELinux is enabled on the system.
    </para>

    <para>
      The interface of the helper - command line options, and input/output
      data format are internal to the <emphasis>pam_unix</emphasis>
      module and it should not be called directly from applications.
    </para>
