title: Access control of a Module in Yii2
body: <p>I am having a trouble with login part. 
  I read this topic : <a href="http://www.yiiframework.com/wiki/771/rbac-super-simple-with-admin-and-user/" rel="nofollow">http://www.yiiframework.com/wiki/771/rbac-super-simple-with-admin-and-user/</a> . 
  Then i follow its steps, but in step 6. it only configs for just one Controller. I have a Module called Admin with many controllers in it and i don't know how to apply this access control to the whole module. Can anyone help me ?
  Sorry for my bad English.</p>
