Can't get the network credentials to work

Question

So I've been working with DotNetOpenAuth for a while, Today I needed to add support for provider that forces me to send the secret key with Basic authentication (I've been using an old version and only Post parameters)

I've tried using ClientCredentialApplicator.NetworkCredential, it didn't work. Then per the advice here, I've made my own ClientCredentialApplicator.

I still didn't work, I put breakpoints in ApplyClientCredential and they never hit.

I upgraded to the latest version (4.3.0.0), which should have this fix.

Everything works but there's no Authorization header, and the remote server answers with 301 error (which makes me think it is the same problem as the commit - the Authorization info is not added to the request until the server answers with Unauthorized and the provider I'm using answers with 301 when there's no Authorization header)

Answer 1

Here is the code. It works with me, when using WebClients and FtpWebRequests, e.t.c

using System.Net;

---

NetworkCredential credentials = new NetworkCredential("user","pass");
request.Credentials = credentials;

Hope it helps :)

Answer 2

I had a similar requirement: a OAuth2 provider that requires HTTP Basic Authentication. This solution worked for me:

var authServer = new AuthorizationServerDescription { AuthorizationEndpoint = new Uri(AuthorizeUrl), TokenEndpoint = new Uri(AccessTokenUrl) };
var authClient = new WebServerClient(authServer, ConsumerKey, ConsumerSecret)
{
    ClientCredentialApplicator = ClientCredentialApplicator.NetworkCredential(ConsumerSecret)
};

There's an issue when using the DotNetOpenAuth.OAuth2.ClientCredentialApplicator.NetworkCredentialApplicator constructor which takes an instance of System.Net.NetworkCredential. The ApplyClientCredential method uses the instance ClientSecret property not the Password property from the credentials (see below).

public override void ApplyClientCredential(string clientIdentifier, HttpWebRequest request)
{
  if (clientIdentifier == null)
    return;
  if (this.credential != null)
    ErrorUtilities.VerifyHost((string.Equals(this.credential.UserName, clientIdentifier, StringComparison.Ordinal) ? 1 : 0) != 0, "Client identifiers \"{0}\" and \"{1}\" do not match.", (object) this.credential.UserName, (object) clientIdentifier);
  OAuthUtilities.ApplyHttpBasicAuth(request.Headers, clientIdentifier, this.clientSecret);
}

I know this question is old, hoping this helps someone else searching for a solution.
