IE: Choose a digital certificate from a blank, empty list
I've created a web application that I've hosted with IIS 7 on a Windows Server 2008 machine. I've loaded a security certificate for secure.xxxxx.com.

When I browse to the web site with Microsoft Internet Explorer, I get this prompt:
Choose a digital certificate
Identification
The website you want to view requests identification.
Please choose a certificate.
There are no certificates. It's an empty, blank list.
If I click either OK or Cancel, then the page loads just fine. There's no warning or other indication from Internet Explorer that there is a security issue.
The Apple Safari browser won't display the page at all.
Safari can't open the page.
Safari can't open the page xxxxx because it couldn't establish a secure connection to the server xxxxx.

Both Mozilla Firefox and Google Chrome load the web site perfectly with no hassles.

Why might Microsoft Internet Explorer and Apple Safari fail to load my web site properly?
I found the solution at forums.iis.net.
In IIS I modified the SSL Settings for my web site.

I changed "Client certificates" from "Accept" to "Ignore".
Before:
IIS SSL Settings accept client certificates http://img185.imageshack.us/img185/548/ssl2om9.gif
After:
IIS SSL Settings ignore client certificates http://img185.imageshack.us/img185/4945/ssl3kx6.gif
The web site now loads perfectly in Microsoft Internet Explorer and Apple Safari as well as Mozilla Firefox and Google Chrome.
