Hello

I want to consume a web service from a winform .net application (developed by an other firm in asp.net) and it requires an authentification

So i tried to send a credential to it, but i receive an http 401  error unautorized

So i checked out what is the soap message sent from my client, but it doesn't contain any authentification in the header 

This is my code :

CredentialCache v_Credential = new CredentialCache();

           .InputService v_Service = new InputService();

            string login = "test";

           string password = "test";

            v_Credential.Add(new Uri(v_Service.Url), "Basic", new NetworkCredential(login,password,""));

            v_ServiceScoda.Credentials = v_Credential;

            v_Service.Method1();

I tried also to change 'Basic' to 'Negotiate', to add a domain but nothing works

and also saw on forums, that i needed to instantiate a class that derives from soapheader developed by the creator of the web service : http://www.codeproject.com/KB/cpp/authforwebservices.aspx

so what is the good way ? use the specific class, or the properties 'Credentials'

and why doesn't it work on my example

Have you tried this: 

v_ServiceScoda.Credentials = CredentialCache.DefaultCredentials;

what for ?

the web service expects a login password, not the default credential of the client

sorry,my mistake.

BUT I've noticed that you didn't provide the domain name which is required.

And for checking,If you type the url of your webservice in you browser,and provide these credentials,does it work or not.

impossible to call a web service on a browser, not supported

and the domain is not required

it doesnt answer my questions, why the wsdl doesnt contain any required information about security, and why my soap message doesnt contain the security
