I'm running Apache 2.2.11 configured as a reverse proxy. The "front side" of the proxy works fine, as does the back end until we enable SSL Certificate based authentication on the back (Client) side of the proxy.
My HTTPD conf file contains:
Per the documentation, I have combined the key and certificate in to the "myauth" file. I am using the same certificate and key used to secure the HTTPS connection on the front side of the proxy. This was concatenated cat ../server.key ../server.pem >> myauth
The private key is not password protected.
My Apache log indicates:
[debug] ssl_engine_kernel.c(1526): Proxy client certificate callback: (obsucredhostname.com:8010) entered [debug] ssl_engine_kernel.c(1571): Proxy client certificate callback: (obsucredhostname.com:8010) no client certificate found!?
Is it possible to use the same certificate key pair as is used to secure the front end SSL? My front-end is secured by godaddys signing service. Or, am I required to use a separate and unique pair?
