<h3>Summary</h3>

    <p>This module provides authorization capabilities so that
    authenticated users can be allowed or denied access to portions
    of the web site. <code class="module"><a href="../mod/mod_authz_user.html">mod_authz_user</a></code> grants
    access if the authenticated user is listed in a <code>Require user</code>
    directive. Alternatively <code>Require valid-user</code> can be used to
    grant access to all successfully authenticated users.</p>

    <p>Setting the <code class="directive">AuthzUserAuthoritative</code>
    directive explicitly to <code>Off</code> allows for
    user authorization to be passed on to lower level modules (as defined
    in the <code>modules.c</code> files) if there is <strong>no
    user</strong> matching the supplied userID.</p>

    <p>By default, control is not passed on and an unknown user
    will result in an Authentication Required reply. Not
    setting it to <code>Off</code> thus keeps the system secure and forces
    an NCSA compliant behaviour.</p>
