Account Mappings - Basic
You can configure your Web server to authenticate users who log on with client certificates by creating a one-to-one mapping that relates the contents of a specific client certificate to a Windows NT user account. To map multiple certificates to a single account you must define a one-to-one mapping for each client certificate.
One-to-one mappings require you to have access to a text (ASCII) copy of the userÆs client certificate. Since this may not always be possible, nor feasible, you may want to use Active Sever Pages to create a script for extracting client certificate information from the userÆs HTTP request header. For more information, consult your Web server documentation.
