Validating Digest Authentication RRS feed

  • Question

  • Hi All,

    I am trying to connect to one URL using digest authentication (HttpWebRequest+NetworkCredential ). I need to validate the user name and password i.e need to check for wrong username and password. Here is the code, I have implemented. Even when I am giving wrong username and password. I am getting httpresponse status code OK means 



                    Uri myUri = new Uri(URL);
                    httprequest = (HttpWebRequest)HttpWebRequest.Create(myUri);

                    NetworkCredential mynetworkcredential = new NetworkCredential(strUser, strPassword);
                    mycredentialcache = new CredentialCache();

                    mycredentialcache.Add(myUri, "Digest", mynetworkcredential);
                    httprequest.PreAuthenticate = true;
                    httprequest.Credentials = mycredentialcache;
                    httprequest.UserAgent = "MSIE";
                    httprequest.AllowAutoRedirect = true;
                    httprequest.KeepAlive = true;

                    HttpWebResponse httpresponse = (HttpWebResponse)httprequest.GetResponse();

    What could be the problem ? Can anybody tell me how to validate wrong username and password ?

  • Hi Mrutyunjaya,

    Please try to test the following code, it shows how to request a web page using the HttpWebRequest class with digest authentication method enabled.

    private string LoadHttpPageWithDigestAuthentication(string url, string username, string password)
        Uri myUri = new Uri(url);
        WebRequest myWebRequest = HttpWebRequest.Create(myUri);
        HttpWebRequest myHttpWebRequest = (HttpWebRequest)myWebRequest;
        NetworkCredential myNetworkCredential = new NetworkCredential(username, password);
        CredentialCache myCredentialCache = new CredentialCache();
        myCredentialCache.Add(myUri, "Digest", myNetworkCredential);
        myHttpWebRequest.PreAuthenticate = true;
        myHttpWebRequest.Credentials = myCredentialCache;
        WebResponse myWebResponse = myWebRequest.GetResponse();
        Stream responseStream = myWebResponse.GetResponseStream();
        StreamReader myStreamReader = new StreamReader(responseStream, Encoding.Default);
        string pageContent = myStreamReader.ReadToEnd();
        return pageContent;

    In addition, we can validate a username and password in Active Directory

    // create a "principal c

    ontext" - e.g. your domain (could be machine, too) using(PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN")) { // validate the credentials bool isValid = pc.ValidateCredentials("myuser", "mypassword"); }

    Hope it helpful for you.

    Good luck!
