Hi, in my understanding authentication using client certificates is just a cryptographic validation of a public/private keypair over a already established ssl-secured channel. For example, it is possible to use a official certificate for the ssl channel and my own ca for client certificate validation. Meanwhile i tried to find the suitable RFC to get details about this problem - probably http://tools.ietf.org/html/rfc5246#page-55 might be the right one. Does anybody have the suitable background knowhow of the RFC and mod_ssl to help me to find out source of the problem? Regards Marc Am 25.06.2014 21:15, schrieb Jens-U.
