Failed when validating user through authentication service

You certainly do not have any user interface for web services.Also, you must be knowing that forms authentication works based on an authentication cookie that is passed to and from with each request made to the application.The first we need to do is to make appropriate changes to web.config to enable forms authentication.The following markup shows this in detail: Here, we set authentication mode to "Forms" and deny access to anonymous users. He is a published author and has authored or co-authored books for Apress and Wrox press.Based on this validation you will display some error or success message. In fact in this article I am going to show how to do just that. Before understanding the problem in implementing forms authentication with web services, let us first see how forms authentication works in a typical scenarios.Forms authentication works very well with web forms. As you can see, Forms Authentication greatly depends on a physical login page to accept the user credentials.If the authentication succeeds, CAS returns the client to the application, passing along a service ticket.The application then validates the ticket by contacting CAS over a secure connection and providing its own service identifier and the ticket.

Thus, a webmail client and a webmail server can all implement CAS. CAS 2.0 introduced multi-tier proxy authentication. Several other CAS distributions have been developed with new features.Service1() Dim cc As New Cookie Container() Dim sessioncookie As Cookie Dim cookiecoll As New Cookie Collection() x. Its purpose is to permit a user to access multiple applications while providing their credentials (such as userid and password) only once.The CAS protocol involves at least three parties: a client web browser, the web application requesting authentication, and the CAS server.It may also involve a back-end service, such as a database server, that does not have its own HTTP interface but communicates with a web application.
