title: Sitecore Security Access Rights
body: <p>I have Role A. Role A is denied access to Item X.
  Then there is Role B.
  Role B should be granted access to Item X. 
  Role B is Member of A.</p>
  
  <p>So a user that is in Role A should not have Access. And a user that is in Role B should have access.</p>
  
  <p>I have seen that deny cant be overwritten, is there a workaround?
  I need to set the rights in code behind.</p>
  
  <p>Thanks</p>
