The HTTP request is unauthorized with client authentication scheme 'Basic'.The authentication header received from the server was 'Basic realm="

Question

I am trying to access a Soap webservice (HTTP) which requires authentication.I am using WCF to consume the service. I am getting error Message as The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Basic realm="weblogic"'.

Any help is appreciated, thank you.

This is what my code looks like:

var binding = new BasicHttpBinding();               
            binding.MaxBufferSize = 2147483647;

            binding.MaxReceivedMessageSize = 2147483647;
            binding.Security = new BasicHttpSecurity
            {
                Mode = BasicHttpSecurityMode.TransportCredentialOnly,
                Transport = new HttpTransportSecurity()
                {
                    ClientCredentialType = HttpClientCredentialType.Basic
                }
            };
            var endpoint = new System.ServiceModel.EndpointAddress(configuration["webserviceAddres"]);
            servicio = new ConsultaMontosOperadosFondosClient(binding, endpoint);
            servicio.ClientCredentials.UserName.Password = MyPass;
            servicio.ClientCredentials.UserName.UserName = MyUser;

Answer 1

If the service is not over https, then try adding the realm: (I am not sure it is weblogic or not, just going by what you posted in your error)

binding.Security = new BasicHttpSecurity
{
    Mode = BasicHttpSecurityMode.TransportCredentialOnly,
    Transport = new HttpTransportSecurity()
    {
        ClientCredentialType = HttpClientCredentialType.Basic,
        Realm = "weblogic"
    }
};

Enable the basic authentication in IIS authentication module, and then provide the username/password.

BasicHttpBinding binding = new BasicHttpBinding();
            binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
            ServiceReference1.WebService1SoapClient client = new ServiceReference1.WebService1SoapClient(binding, new EndpointAddress("http://10.157.13.69:8001/webservice1.asmx"));
            client.ClientCredentials.UserName.UserName = "administrator";
            client.ClientCredentials.UserName.Password = "abcd1234!";
