Web site with RSA authentication

Hi!

I'm creating a web site where users can log in using their RSA token and username, however I can't find much information about RADIUS and RSA Authentication. Is there any way to use RADIUS with IIS? Or do I have to use the RSA SecurID Authentication Agent for IIS? I'd like to avoid exporting the sdconf.rec file for security reasons.

Thanks for any replies!
