Consuming web services with claims-based authentication - SoapServerException

We have an application that periodically pulls data from a SharePoint list and integrates with another application. We've been using it for more than a year without a problem. Recently, however, we switched our farm to use claims-based authentication... and there went the app.

My code, at a high level, does the following:

SPWebRefs.Lists spl = new SPWebRefs.Lists();
spl.Credentials = System.Net.CredentialCache.DefaultCredentials;

//Build request here


XmlNode listItems = spl.GetListItems("My list", view, query, viewFields, null, queryOptions, null);

I get an "Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown" exception right there.

I'm looking through Fiddler, and I get the 401 challenge, quickly followed by a 200 response, which I assume means I'm in. But then I get a 500 error as soon as the GetListItems method is invoked.

I've tried this against a 2010 instance as well as a 2013 farm that we're getting ready to deploy. Same situation.

I'm using the 4.0 Framework at this point, but I've considered testing it out against the 4.5 Framework, which includes some new APIs for claims authentication. Would that make any difference?

Any thoughts would be greatly appreciated. Thanks so much in advance!

You must call SharePoint's Authentication WebService first. You will get a cookie from it, which you can pass to the Lists WebService.

See a sample here: http://www.tonytestasworld.com/post/2009/06/04/How-To-Authenticate-and-Use-SharePoint-Web-Services-in-an-FBA-SharePoint-site.aspx
