title: Onvif authentication with axis camara P1344 c#
body: <p>I'm completely stuck with <strong>ONVIF</strong> authentication. I think I've tried everything or at least almost everything and I don't find enough information on the Internet. I have created the stub client using svcutil, my code to do the authentication is (one of them because I have tried a lot of things):</p>
  
  <pre><code> string uri = "http://140.0.22.39/onvif/services";
  
   EndpointAddress serviceAddressPrueba = new EndpointAddress(uri);
   HttpTransportBindingElement httpBinding = new HttpTransportBindingElement();
   httpBinding.AuthenticationScheme = AuthenticationSchemes.Digest;
   var messegeElement = new TextMessageEncodingBindingElement();
   messegeElement.MessageVersion = MessageVersion.CreateVersion(EnvelopeVersion.Soap12, AddressingVersion.None);
  CustomBinding bindprueba = new CustomBinding(messegeElement, httpBinding);
  DeviceClient clientprueba = new DeviceClient(bindprueba, serviceAddressPrueba);
  string passwordDigestBase64;
  //HERE I PUT THE CODE TO ENCRYPT THE PASSWORD.
  PasswordDigestBehavior behavior1 = new PasswordDigestBehavior("root",passwordDigestBase64);
  clientprueba.Endpoint.Behaviors.Add(behavior1);
  string d1;
  string d2;
  string d3;
  string d4;
  
  clientprueba.GetDeviceInformation(out d1, out d2, out d3, out d4);
  </code></pre>
  
  <p>After this there is the following error:</p>
  
  <pre><code>{"The remote server returned an unexpected response: (400) Bad Request."}
  </code></pre>
  
  <p>I will be very, very grateful if you please could help me with any information to solve this.</p>
