Hi List,
I have an application server in an internal DMZ for which I use an Apache2 as a reverse proxy. The overall communication works flawlessly. Clients connect to the Apache and it passes the communication requests through to my internal application server - by the way it is an SAP XI.
Now I added SSL to my setup and this too works perfectly. A client uses SSL to contact the application server. The Apache as reverse proxy terminates the SSL connection and then connects to the internal application server via SSL.
But now I want the external client to authenticate itself to the application server via client certificate and this won't work at all. I mean as I see it in normal SSL communication the client certificate is taken by the apache wich will not use it because he is not configured to check for client certificates. The application server again is supposed to authenticate the client via its certificate which fails because the Apache does not pass the certificate through to him.
Is there any way of configuring the apache to terminate the SSL connection but pass the client certificate from the outside client to the internal application server???
Thanks in advance,
Christian
Ps.: I have added my httpd.conf part that deals with the XI backend
<VirtualHost 172.30.210.210>
