  33 <h3>Summary</h3>
  34
  35     <p>This module provides authorization capabilities so that
  36     authenticated users can be allowed or denied access to portions
  37     of the web site. <code class="module"><a href="../mod/mod_authz_user.html">mod_authz_user</a></code> grants
  38     access if the authenticated user is listed in a <code>Require user</code>
  39     directive. Alternatively <code>require valid-user</code> can be used to
  40     grant access to all successfully authenticated users.</p>

  64     <p>Setting the <code class="directive">AuthzUserAuthoritative</code>
  65     directive explicitly to <code>Off</code> allows for
  66     user authorization to be passed on to lower level modules (as defined
  67     in the <code>modules.c</code> files) if there is <strong>no
  68     user</strong> matching the supplied userID.</p>
  69
  70     <p>By default, control is not passed on and an unknown user
  71     will result in an Authentication Required reply. Not
  72     setting it to <code>Off</code> thus keeps the system secure and forces
  73     an NCSA compliant behaviour.</p>
