Certificate authentication for Web-based users

Hi,

I’m trying to understand how certificate authentication works for my Web-based users, and I’m not sure of how to design my application to check for certificates, authenticate using their certificate, etc. Is there a property I select for the database, some sort of tag I use, or something ridiculously easy that I just don’t see? I tried combing the Iris Today articles and the Sandbox, and couldn’t find this information…maybe I just missed it, I dunno. If anyone can point me to an article or explain how to design a Web-based application around this stuff, I would really appreciate it.

Thanks!

Sam
