Authentication failed while calling WCF service from ASP.NET

Question

Platform: VS 2008, .NET 3.5, C#, Oracle 11g

I've created a WCF service which takes some data elements and then inserts them into a database table and returns an integer. I've also created a small ASP.NET web app to test that service. The test web app only has a page with the fields and a button, clicking that button actually calls the web service to insert the data and return a integer value.

The steps I took:

• Build the WCF service
• Publish the WCF Service
• Generate the proxy class (.cs) and app.config using svcutil
• Build the test asp.net app and add the proxy class and config settings as generated on the above step.
• Ruin the test app

It works fine when I deploy both the WCF and the test web app on my computer - Windows XP, IIS 5.1. But, whenever I'm trying to deploy them on a remote server it doesn't work. When I'm trying to consume the service (deployed on remote server - Windows 2003 server, IIS 6) I'm getting the following error:

The request for security token could not be satisfied because authentication failed.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ServiceModel.FaultException: The request for security token could not be satisfied because authentication failed.

Following are the .config files content:

Answer 1

Could be related with security configuration of wcf service, to be specific, Windows credential type requires valid domain username and password information.

Try providing the following attributes on clientside;

proxy.ClientCredentials.Windows.ClientCredential.UserName = "UserName ";
proxy.ClientCredentials.Windows.ClientCredential.Password = "Password ";
proxy.ClientCredentials.Windows.ClientCredential.Domain = "Domain ";
