title: setting different access for different module
body: <p>I want set different access for different modules.</p>
  
  <p>I tried out</p>
  
  <pre><code>$this-&gt;allow($role, $module, $controller, $action);
  </code></pre>
  
  <p>or </p>
  
  <pre><code>$this-&gt;allow($role, $module . ':' . $controller, $action);
  </code></pre>
  
  <p>But this does not seem to work.</p>
  
  <p>Any ideas??</p>
