SharePoint Web Services, .NET 3.5, and Authentication Issues
Thursday, April 9th, 2009
The .NET Framework 3.5 has changed how it invokes and discovers web services, and as a result you may find yourself struggling with some properties and fields that in the past you were used to finding in the proxy class of the web service itself.
I had just this problem when it came to security settings and the user that I was authenticating as while trying to call an authenticated web service.
After quite a few searches on Google I was able to piece together the fix to the problem.
The error that I was receiving was as follows:
The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.
In order to change this, you need to go to the app.config created when you bind to a web service, and change the security section to the following:
Rebuild the project and you should be good to go with an authenticated web service call.
