Configure Apache to send SSL Client certificate to backend server

Hi All;
i want to configure Apache so that it receives a client certificate, an passes it to another server.
I'm using:
- apache 2.0.65 on windows
- the backend server is an apache-based solution (IBM HTTP Server)
I tried this config:

<VirtualHost *:443>
ServerName apacheserver.domain.com
SSLEngine on
SSLProxyEngine on
SSLCertificateFile "e:/Apache/Apache2/conf/server.cer"
SSLCertificateKeyFile "e:/Apache/Apache2/conf/server.key"
SSLCACertificateFile  "e:/Apache/Apache2/conf/certca.cer"
SSLVerifyClient require
SSLVerifyDepth 2
ProxyPreserveHost on
ProxyRequests off
<Proxy *>
AddDefaultCharset Off
Order deny,allow
Allow from all
</Proxy>
# initialize the special headers to a blank value to avoid http header forgeries
RequestHeader set SSL_CLIENT_S_DN    ""
RequestHeader set SSL_CLIENT_I_DN    ""
RequestHeader set SSL_SERVER_S_DN_OU ""
RequestHeader set SSL_CLIENT_VERIFY  ""
<Directory />
# add all the SSL_* you need in the internal web application
RequestHeader set SSL_CLIENT_S_DN "%{SSL_CLIENT_S_DN}e"
RequestHeader set SSL_CLIENT_I_DN "%{SSL_CLIENT_I_DN}e"
RequestHeader set SSL_SERVER_S_DN_OU "%{SSL_SERVER_S_DN_OU}e"
RequestHeader set SSL_CLIENT_VERIFY "%{SSL_CLIENT_VERIFY}e"
ProxyPass  https://192.168.10.191/
ProxyPassReverse  https://192.168.10.191/
</Directory>
</VirtualHost>

Code (markup):

when i try this config, i have this error on the error.log file of apache:

any ideas?

 

Have you upload on server the ssl files ?

1. SSLCertificateFile "e:/Apache/Apache2/conf/server.cer"
2. SSLCertificateKeyFile "e:/Apache/Apache2/conf/server.key"
3. SSLCACertificateFile "e:/Apache/Apache2/conf/certca.cer"
