Ssl – Access denied error when running site with SSL

iis-7ssl

i've setup a SSL certificate to use in a website i'm working on. The problem is that when "Require SSL" is checked in iis, i get the following error while trying to access the site:

403 – Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.

If that checkbox is not checked, the site works fine (i'm not sure why, but i can even access it through SSL).

Not sure if it makes any difference, but my company has an ISA server that we use as a proxy / firewall.

Thanks, Gonzalo

The Require SSL checkbox should have 3-option radio button for "Client Certificates". What have you selected there? If you have it set to Require, then it will require client authentication and if you don't specify a client certificate, it will give you the access denied. If you set it to ignore or accept, it will not be a fatal error if you don't specify client certificate.
