Could not establish secure channel for SSL/TLS with authority '*'

Question

I must consume a PHP webservice which has a SSL certificate. My .net 3.5 Class library references the webservice with 'Add Service references' in Visualstudio 2010 (WCF right?).

When calling the main method of the webservice I receive;

Could not establish secure channel for SSL/TLS with authority '{base_url_of_WS}'.

I tried a lot, like

System.Net.ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);   public bool CheckValidationResult(Object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)     {         return true;     } 

But It wouldn't work. Also I have the certificate installed on my own machine.

*Extra info; When I use the wsdl location in 'Add service reference' the same error occurs. Before I tried it, I worked with a static wsdl.

This was exact the problem I was facing. At some other article I got a hint to change the configuration. For me this works:

<bindings>   <basicHttpBinding>     <binding name="xxxBinding">       <security mode="Transport">         <transport clientCredentialType="Certificate"/>       </security>     </binding>   </basicHttpBinding> </bindings>
