The following illustration depicts the method of authenticating users to the Web service when your application is deployed with a report server configured to use a custom authentication extension.

As shown in Figure 2, the authentication process is as follows: When the Web service successfully authenticates a user through the security extension, it generates a cookie that is used for subsequent requests.

An example of an implementation of Logon User looks like this: method of the Reporting Services Web service is used to submit credentials to the report server for authentication.
