Authentication problem between ASP.Net Webforms app and a ASP.Net webservice

Question

I got a ASP.Net webforms app which is using Forms authentication. It needs to authenticate against a webservice which uses windows authentication (+ impersonation).

I've tried (amongst other things) to supply credentials by using:

service.Credentials = new NetworkCredential(myUserName, thePassword, theDomain)

The problem is that I get 401 from the webservice no matter what I try.

I am doing exactly the same as this (by the sounds of it) and here is the way I construct the credentials.

var service = new MyService();
var netCredential = new NetworkCredential("user", "pwd", "domain");
var credentialCache = new CredentialCache
                          {
                              {new Uri(service.Url), "Basic", netCredential}
                          };
service.Credentials = credentialCache;

Which authentication methods have you activated in IIS for your webforms app and for your webservice? Which IIS version are you running?

The Web service is hosted on IIS7 and Authentication = Basic and Impersonation = true. The Web App is running on a different server which is also IIS7 and requires Windows Authentication.

The problem was that identity that the Application Pool that the Web service run on wasn't allowed to impersonate.
