    3. Click All settings to display the Settings blade and click Required permissions on that blade.
    4. On the Required permissions blade, click Windows Azure Active Directory to display the Enable Access blade.
    5. Select the permissions to be granted to your application and click Save to close the Enable Access blade. You may need the consent of the administrator of your Azure portal to eventually validate the grant.
