In most applications that are using membership, there are additional features that would be nice to have on the client The ability to change the logged-in user without causing a postback is one of them Often in business applications, there is a need to have a manager override entries made in a data-entry screen by a user of limited rights The ability to switch user context using the authentication service without causing a postback would provide a nice alternative to the longer process of switching users via the membership controls To demonstrate this, we look at an order-entry screen that provides the ability to add a discount In most cases, you would not want just any employee to do this Therefore, we need a manager override to accomplish this This is where the ability to log in on the client comes into play In this case, we enable a manager to log in to the application, make a change, and then log out, thus resetting the credentials to the user The order-entry screen shown in Figure 911 contains a Discount drop-down, access to which requires a user with manager rights The Enable link next to the drop-down brings up the Login screen shown in Figure 912, which enables a user to log in with manager credentials, enabling the drop-down and enabling the user to discount the order The call to the authentication service is shown in Listing 913 It passes in the username and password provided by the user and attempts to log the user in A successful login validates the user and enables the drop-down One thing that we are not checking for in this case is the role that the newly logged-in user is in This will be the topic of the next section, as we cover more of what the application services provide on the client
