I had a server with server side ssl working.
I've added :
SSLVerifyClient require SSLVerifyDepth 1 SSLCaCertificateFile /etc/ssl/certs/MyCA.crt
And now I get a connection reset every time I try to load a page. There are no errors in the error.log. And no errors on Apache restart.
The client certificate is not yet installed in the client. The browser is FF 23.01. I should be getting an error that says, "This site requires a certificate".
