  97.     <p>Setting the <code class="directive">AuthzGroupFileAuthoritative</code>
  98.     directive explicitly to <code>Off</code> allows for
  99.     group authorization to be passed on to lower level modules (as defined
  100.     in the <code>modules.c</code> files) if there is <strong>no
  101.     group</strong> matching the supplied userID.</p>
  102.  
  103.     <p>By default, control is not passed on and an unknown group
  104.     will result in an Authentication Required reply. Not
  105.     setting it thus keeps the system secure and forces an NCSA
  106.     compliant behaviour.</p>

  109.       <p>Do consider the implications of allowing a user to
  110.       allow fall-through in his <code>.htaccess</code> file; and verify
  111.       that this is really what you want; Generally it is easier to just
  112.       secure a single <code>.htpasswd</code> file, than it is to secure
  113.       a database which might have more access interfaces.</p>
