Enabling Authentication in LightSwitch

This lesson shows how to enable authentication for a LightSwitch application.

Most business applications have security features to prevent unauthorized users from reading, manipulating, or deleting data. In LightSwitch, you can make your application more secure by implementing authentication. This means that users must identify themselves, and the application must verify the user’s credentials, before the user can access the application. The first step in securing your application is to enable authentication.

To enable authentication

  1. In Solution Explorer, open the shortcut menu for the My First Application node, and then choose Properties.

  2. In the My First Application Properties window, choose the Access Control tab.

  3. In the Select the type of authentication to use: list, choose the Use Windows authentication option button.

    Enabling Windows authentication

    The application will now require users to identify themselves to access the application.

This lesson showed how to enable Windows authentication for your application. With Windows authentication, the application authenticates a user based on the same credentials that the user provides to log on to the computer that's running the application. No additional user name or password is required.

Note Note

While you develop your application, you won't be prompted for a user name and password; you'll automatically be logged on as a test user.

The other authentication option is Use Forms authentication, which the application itself manages. The application administrator maintains a list of authorized users and passwords, and a user must supply a user name and a password to access the application. Forms authentication is a good choice when many users share one computer under one account.

When you publish an application that uses authentication, you’ll need to define a default administrator who can add or remove users and roles. If authentication is enabled and you haven’t defined a default administrator, you won’t be able to access the published application. See Administration.

In the next lesson, you’ll learn how to restrict access to parts of the application instead of the application as a whole.
