IISExpress ClientCertificate Setup Steps

Question

I am trying to configure a simple web site to require client certificates on IISExpress.

My configuration is according to this archived jasonrshaver.com post.

<site name="XXXX" id="3">
 <application path="/" applicationPool="Clr4IntegratedAppPool">
  <virtualDirectory path="/" physicalPath="XXXX" />
 </application>
 <bindings>
  <binding protocol="http" bindingInformation="*:65360:localhost" />
  <binding protocol="https" bindingInformation="*:44300:localhost" />
 </bindings>
</site>
...
<access sslFlags="Ssl, SslNegotiateCert" />
...
<iisClientCertificateMappingAuthentication enabled="true">
</iisClientCertificateMappingAuthentication>

It is a simple MVC4 Web App that outputs the ClientCertificate data.

The problem is that when I browse to https I am not prompted for a certificate in browser. I do have 4 certificates that can be used; they are configured in Chrome

Any help appreciated. Thank you.

Answer 1

There was a certificate problem, not a IISExpress configuration problem.

I had no certificates that could be used for client authentication. After installing a certificate with Intended Purposes everything worked fine.

So the above configuration works just fine.
