Map Client Certificates One-to-One (IIS 7)
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
When you want each Windows user account to map to a single client certificate, use one-to-one IIS certificate mapping. This mapping provides added protection for your server because the certificate sent by the client must be identical to the copy of the client certificate stored on the server. Before you can map client certificates, you must enable Secure Sockets Layer (SSL) for your site.
Important
If you use IIS one-to-one certificate mapping, you cannot use Active Directory certificate mapping.
