There are some articles about how to configure the Mutual Certificate authentication on IIS. But the steps are not very clear. Here is a detailed step by step procedure to configure the IIS client certification mapping authentication for IIS 7.

Firstly, there are several pre-requisites.

  1. Trusted CA root certificate.

  2. Server Certificate from a trusted CA.

  3. Client Certificate from a trusted CA.

Server side:

Install the server certificate on the server side.

1. Open mmc console, add the certificate for the Local Computer.

You can also configure this by install the Client Certificates UI by this link. https://www.iis.net/downloads/community/2009/08/iis-70-ui-module-for-client-certificate-mapping

On the client side:

1. Open MMC console and import the client certificate and CA root certificate. Import them to the Current User account.

2. Check if the client certificate exist in the content->certificate as below.

3. Try to visit the website and the client certificate will pop up. This is not popped up if there is only one client certificate by default. Here I configure the IE browser to prompt the dialog even only one client certificate is available. Please do it as below.

    You may want to check the IE settings:Configuring IE with client certificateOn the workstation open IE -> go to internet options -> Content -> CertificatesClick on import and select the client certificate Under Internet Options -> Security -> select Custom level and enable the setting “Don’t prompt for client certificate selection when only one certificate exists” When there only one client certificate in personal store the site connection would not prompt for client certificate selection when the above option is selected
