I want to set the value of SSL_CLIENT_S_DN_CN on the RequestHeader in apache, the below does not work...
SSLOptions +StdEnvVars
SSLUserName SSL_CLIENT_S_DN_CN
ProxyPass http://x.x.x.x/
ProxyPassReverse http://x.x.x.x/
Header add X-FILTER-Username %{SSL_CLIENT_S_DN_CN}
RequestHeader set X-FILTER-Username %{SSL_CLIENT_S_DN_CN}
any idea how it can be done?
