WCF Fix-The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'NTLM'.

I thought I'd done a post on this error previously, but I double checked google and I obviously hadn't.

The Problem
When calling WSS / SharePoint web services (such as Lists.asmx) via WCF, you will normally get this error if you leave the settings as configured by the “Add Service Reference Wizard” :

“The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'NTLM'.”

The Solution

You must specify a non-anonymous impersonation level for your ClientCredentials. Just specifying a username and password for your WCF Service reference's ClientCredentials.UserName.UserName and ClientCredentials.UserName.Password is not sufficient to resolve the problem.

In particular (When SharePoint server is on different domain):

ServiceReference1.ListsSoapClient client = new ServiceReference1.ListsSoapClient();
client.ClientCredentials.Windows.ClientCredential = new System.Net.NetworkCredential("username", "password", "domain");
client.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Identification;

Of course, when on same domain, don’t have to pass in the Windows.ClientCredential information. You can also set the above values in app.config configuration elements rather than code, but I won't cover that here.

You can use (with descending levels of security):

Details on these impersonation levels can be found at:

Config Changes

<binding name="ListsSoap">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
<endpoint address="http://servername/_vti_bin/Lists.asmx"
binding="basicHttpBinding" bindingConfiguration="ListsSoap"
contract="ServiceReference1.ListsSoap" name="ListsSoap1" />

I used similar code to call to CRM4.0 service in a different domain, but I still did not make it work. I got message "The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.".

Hi David,
You really saved my day today

I used the same security settings NTLM for my web.config file.
it resolved the error which i used to get
The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'

Thanks this helped a lot, I was using basic authentication, so only used the web.config part and provided user Id and Password like this:

MyService client = new Myservice();

client.ClientCredentials.UserName.UserName = @"domain\UserName";
client.ClientCredentials.UserName.Password = "Password";
var response = client.GetCurrentTransmissions("F2FD76FD-5DF7-4915-972D-703C403F932E");

And My web.config looks like this :

When you are brash and indiscreet and decide to buy Tramadol 100mg online you could end up being addicted to it.
