 Extend your aspect to enforce an authenticated user when ''@Authenticated'' methods or constructors are executed.
-To model the authentication, we will present the user with an input dialog where he/she can select the role. This is of course a simplification: in production, we would of course have to prompt for login and password and verify these against a password database.

 The code to manage the current role for the user and to present the authentication dialog is shown here:

 As long as the user is not authenticated, we keep presenting him the authentication dialog. In other words, the actual access control check can be as simple as:
-<code>
+<code aspectj>
 while(role == null)
   authenticate();
 </code>
+After implementing the aspect, run the figure editor. You should be presented with the authentication dialog upon drawing the first point. Afterwards, new points can be added without interruption.
