custom authentication of a user s credentials. Assuming the user is valid, the user s roles will be loaded into the business object so they can be used for authorization as the application is used. The PTPrincipal and PTIdentity objects will be implemented in 17. In most cases, you ll be creating similar custom security objects but designed to use your preexisting security database tables. The database created in this chapter and the objects created in s 17 and 18 exist primarily to demonstrate the basic process required for creating your own objects. Figure 3-26 shows the two tables in the database, along with their relationship.

Figure 3-26. Database diagram for the Security database In the Users table, Username and Password are both varchar(20) columns, as is the Role column in the Roles table. Only the Password column allows Null values. All other values are required. Of course, a password should be required as well, but for this simple example, it is left as optional. Finally, there s a Login stored procedure. CREATE PROCEDURE Login ( @user varchar(20), @pw varchar(20) ) AS SELECT Username FROM Users WHERE Username=@user AND Password=@pw; SELECT R.Role FROM Users AS U INNER JOIN Roles AS R ON R.UserName = U.UserName WHERE U.Username = @user and U.Password = @pw RETURN PTIdentity calls this procedure to authenticate the user and retrieve the user s list of roles. As you ll see in 17, PTIdentity determines whether the user s credentials are valid by finding out whether any data is returned from this stored procedure. If no data is returned, then the user s credentials are assumed to be invalid, and the user is not authenticated. On the other hand, if the stored procedure does return data, then PTIdentity stores that data, especially the list of roles to which the user belongs. This list of security roles (not to be confused with the project roles from the PTracker database) is then used for authorization throughout the application. The CanReadProperty() and CanWriteProperty() methods on each business object rely on this data.

The diagram in Figure 7-2 shows a client that requests a security token and then uses it to communicate with two services You can notice that the client only needs to request the token once during this session, which helps reduce the transaction time Another important aspect of the diagram is that two services are using the same authentication broker This is one of the main advantages of this model, because it provides a centralized authentication authority and it allows for easier management of the identity store..

This chapter has started the process of building a sample application that will use the CSLA .NET framework. It s a simple project-tracking application that maintains a list of projects and a list of resources and allows the resources to be assigned to the projects.

myOutput.flush(); myOutput.close(); myInput.close();

The application s design used an object-oriented analysis technique that involved creating use cases that described the various ways in which the users need to interact with the system Based on the use cases, and by using elements of CRC-style design, a list of potential business objects was created and refined That object list was then used to create a preliminary class diagram that showed the classes, their key data fields, and their relationships Based on the diagram, your understanding of the business domain, and the use cases, you were able to refine the design to arrive at a final class diagram that describes the business classes that will comprise the application The next step was to determine the appropriate CSLA NET base classes from which each business object should inherit The editable business objects inherit from BusinessBase, and the collections of editable child objects inherit from BusinessListBase.
