10.4. Working with Login Controls

The ASP.NET 2.0 login controls allow Web designers to quickly develop template-based login interfaces on Web pages for creating, updating, and deleting users as well as authenticating and authorizing users. This form of authentication is called Form-Based Authentication and requires additional setup for membership services, role provides, etc., in the web.config file and a database to store the usernames and passwords. SharePoint Designer provides the following ASP.NET 2.0 login controls:

• ChangePassword: Allows you to create an interface for changing user passwords for a Web site. The control verifies the old password provided as user input before changing the password.

• CreateUserWizard: This control is derived from the Wizard control and allows you to create a step approach for providing an interface for creating new users on a Web site.

• Login: This allows you to create a user interface on a Web page that logs a user into the Web site.

• LoginName: Displays the currently logged-on user's name on the Web page. The control doesn't display anything if you're logged on anonymously.

• LoginStatus: This control determines whether a user is logged on to a Web site. If it finds a user logged on, it displays a link to log out. Otherwise, it offers the user a link to log in that redirects to a page containing the Login control.

• LoginView: This control determines the login status of a user and, based on his or her authentication status, displays different content to the user. For example, this control can be used to display different content to a user based on whether he or she is logged in or not.

• PasswordRecovery: Includes the implementation of the user interface for recovering passwords after confirming the user identity. It also combines the facility to change the passwords.
