NTLM Authentication using RestSharp?

Question

I am trying to use NTLM authentication for my REST calls to TeamCity using RestSharp.

IRestClient _client=new RestClient(_url);
_client.Authenticator = new NtlmAuthenticator            
(System.Net.CredentialCache.DefaultNetworkCredentials);

However it is not working. Please suggest if I am missing something.

How to implement the same using jQuery ajax? I want to consume a rest service which is in.. svc format, and fetch the json data.. — samolpp2, Apr 16 '19 at 06:30

This now appears to be working properly and can be done very easily utilizing the NTLMAuthenticator like so:

RestClient client = new RestClient(_baseURL);
client.Authenticator = new NtlmAuthenticator();

If you use this method don't forget to add a `using RestSharp.Authenticators;` line. – Caltor May 03 '17 at 08:23

no longer works in RestSharp 1.07+, I switched to System.Net.WebClient due to the frustration this caused – Ekus Sep 27 '22 at 02:53

Try this:

var client = new RestClient(_baseURL)
{
     Authenticator = new RestSharp.Authenticators.NtlmAuthenticator()
};

As of RestSharp v107, The NtlmAuthenticator is deprecated.

This worked for me:

var credentials = new NetworkCredential(username, password, domain);
var options = new RestClientOptions(_settings.ServiceEndPoint)
{
 UseDefaultCredentials = false,
 Credentials=credentials
};
var client = new RestClient(options);
