Hello

I have browsed the archives but have not found the answer to this question...

I have stunnel set up to handle https connections. It sits on a CentOS server alongside HAProxy and works fine with every browser except for Internet Explorer.

When I connect with Internet Explorer, I get a blank "Please choose a digital certificate" pop-up.

I am pretty sure I have a configuration issue. Here's what I have:

socket=l:TCP_NODELAY=1 socket=r:TCP_NODELAY=1 options = NO_SSLv2 ciphers=ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM output = /var/log/stunnel.log

[my.host.name] accept=my.external.IP:443 connect=127.0.0.1:8101 xforwardedfor=yes CAfile=/etc/stunnel/GlobalSign.pem cert=/etc/stunnel/my.host.name.pem verify=1

How do we turn off the request for the client certificate in IE?

Here are my details....thanks in advance.
