The NET Framework includes a couple of built-in principal and identity objects that support Windows integrated security or generic security You can also create your own principal and identity objects by creating classes that implement the IPrincipal and IIdentity interfaces from the SystemSecurityPrincipal namespace Implementations of principal and identity objects will be specific to your environment and security requirements However, the framework will include a BusinessPrincipalBase class to streamline the process When you create a custom principal object, it must inherit from BusinessPrincipalBase Code in the data portal ensures that only a WindowsPrincipal or BusinessPrincipalBase object is passed between client and server, depending on the application s configuration In many cases, your custom principal object will require very little code The base class already implements the IPrincipal interface, and it is quite likely that you ll only need to implement the IsInRole() method to fit your needs.

Using a public container is fine for storing content that you don t mind making available to the world, but it s not an acceptable solution if you want to serve content that you want to keep protected. Storing your website assets in BLOB storage is a great way to optimize performance because it takes load away from your web server. In the next chapter, we ll look at how you can take your assets that are stored in BLOB storage and expose them via the Windows Azure Content Delivery Network to make even more performance improvements.

portal will invoke the correct overload based on the parameters provided when the data portal is first called. Inheriting from the ObjectFactory base class is optional but useful. The factory object is responsible for creating and manipulating the business object, including managing the business object s state values as I discuss in 18. The ObjectFactory base class provides the protected methods listed in Table 4-3 to assist in this process.

However, you will need to implement a custom identity object that implements IIdentity Typically, this object will populate itself with user profile information and a list of user roles from a database Essentially, this is just a read-only business object, and so you ll typically inherit from ReadOnlyBase Such an object might be declared like this: [Serializable()] public class CustomIdentity : ReadOnlyBase<CustomIdentity>, IIdentity { // implement here } You ll also need to implement a Login method that the UI code can call to initiate the process of authenticating the user s credentials (username and password) and loading data into the custom identity object This is often best implemented as a static factory method on the custom principal class In many cases, this factory method will look something like this: public static void Login(string username, string password) { CustomIdentity identity = CustomIdentityGetIdentity(username, password); if (identity.

Returning to the podcast example, suppose you decided that you wanted only paid members of your website to be able to download your MP3. In this scenario, you don t want to store the file in a public container; you want to store it in a private container instead.

IsAuthenticated) { IPrincipal principal = new CustomPrincipal(identity); CslaApplicationContextUser = principal; } } The GetIdentity method is a normal factory method in CustomIdentity that just calls the data portal to load the object with data from the database A corresponding Logout method may look like this: public static void Logout() { CustomIdentity identity = CustomIdentityUnauthenticatedIdentity(); IPrincipal principal = new CustomPrincipal(identity); CslaApplicationContextUser = principal; }.

Earlier in this chapter, in the BLOB management web page, you implemented a download link that allowed you to serve files stored in a private container to your users on a public website. Now we re going to expand that technique to a more integrated, reusable solution by doing the following things:

MarkNew() MarkOld() MarkAsChild()

The UnauthenticatedIdentity() method is actually a variation on the factory concept, but in this case, it probably doesn t use the data portal. Instead, it merely needs to create an instance of CustomIdentity, in which IsAuthenticated returns false.

Marks the business object as being a new object Marks the business object as being an old (preexisting) object Marks the business object as a child object

The check of the principal object s type is done to ensure that both the client and server are using the same authentication scheme. If the client is using custom authentication and the server is using Windows integrated security, this exception will be thrown. Custom authentication is discussed more fully in 5.
