This article is very short. In the actual presentation, there was not much time to talk about this so a brief overview was done. Basically, it’s all standard WCF stuff. The idea is that the Silverlight Business Template adds logging in and supports Authentication just like an asp.net application does. It uses the DomainDataSource to do the bridging between the silverlight clientside app, and the web application. Authorization is built into the login module also so that you can assign attributes to your domainservice classes to restrict access.
That is, if you only want people who are logged in able to access one of your methods, you simply tag it as follows with the [RequiresAuthentication] attribute.
If you only want a certain logged in user role to be able to access a certain method, you tag it as follows
This of course solve the server side only. On the client side, you need to call methods that are exposed through the domain data. http://www.silverlightshow.net/items/Silverlight-3-with-Ria-Authentication-service.aspx discusses much of this on the client side.
