title: WSO2 Identity Server - Role management
body: <p>I have few doubts on configuring RBAC in WSO2:</p>
  
  <ol>
  <li>are supported hierarchical roles?</li>
  <li>is it possible to associate different roles to a user depending to a different authorization contexts? I.e. in DeptA a user can access a certain resource since having a manager role, while in DeptB cannot since having normal employee role.</li>
  <li>RBAC can be implemented with XACML policies? Any sample policies available with hierarchical roles? </li>
  </ol>
