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.

Answer 1

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;
