title: Where is the ActiveDirectoryRoleProvider class?
body: <p>I´ve read in MCT Trainer Handbook of course 20486:</p>
  <blockquote>
  <p><strong>Role Providers in ASP.NET 4.5</strong></p>
  <p><strong>ActiveDirectoryRoleProvider</strong>. This provider class is defined in the System.Web.Security namespace, and the provider enables you to use Active Directory as the management model for roles</p>
  </blockquote>
  <p>This namespace (System.Web.Security) has the <strong>ActiveDirectoryMembershipProvider</strong> class but not the <strong>ActiveDirectoryRoleProvider</strong> one? Is this statement correct or I´m missing something?</p>
  <p>Thanks</p>
