Report Builder Role Based Security

From Books Online Help:

In the role-based security model that is implemented for Reporting Services, users who are assigned to the Content Manager role can create and edit reports in Report Builder. Local administrators are automatically assigned to this role.


If you want other users to be able to work with a Report Builder report, you must create a role assignment for them that includes the default role "Report Consumer." Alternatively, you can create a custom role definition. As long as the customized role includes the "Consume reports" task, users who are assigned to that role will have sufficient permission to create and modify reports using Report Builder

However, when I try to give a contact those rights, the "Report Builder" link still does not show up for my users. Is there any other place where I can examine the security rights to see why the Report Builder permission is not granted to my users?
