I am setting up
Apache to do smartcard authentication. The smartcard login is based on client-side SSL certificates handled by an OS driver.
I have currently just one smartcard provider, but in the future there are potentially several of them. I am not sure how
Apache 2.2. handles client-side certifications per Location. I did some quick testing and it somehow seemed that only the last SSLCACertificateFile directive would have been effective and this doesn't sound right.
Is it possible to have different SSLCACertificateFile per Location in
Apache (2.2, 2.4) as described below or is SSL protocol somehow limiting that you cannot have more than one SSLCACertificateFile per IP?
Example potential config below how I wish to handle several SSLCACertificateFile on the same server to allow users to log in with different smartcard provides.
