title: WCF : Could not establish trust relationship for the SSL/TLS secure channel with authority error
body: <p>I have a client site that when a button is clicked it calls a wcf web service. The client site is http, while the url for the web service is https and requires a certificate. I have a valid signed private key certificate I am using. </p>
  
  <p>Everything works fine on my localhost; however, after deploying to a windows 2003 server running iis 6, I get the below error when the web service is called:</p>
  
  <blockquote>
    <p>Could not establish trust relationship for the SSL/TLS secure channel
    with authority "host's url"</p>
  </blockquote>
  
  <p>I added the cert to the store, using same web.config that works locally. I have validated that the web service call finds and sets the valid X509Certificate.</p>
  
  <p>Not sure what I am missing, and I don't want to override the servicepiont manager to return true every time.</p>
  
  <p>Any ideas or things I might looks into?</p>
