SSL_CLIENT_CERT_CHAIN not being passed to backend server
- by nidkil
I have client certificate configured and working in Apache. I want to pass the PEM-encoded X.509 certificates of the client to the backend server.
I tried with the SSLOptions +ExportCertData. This does nothing at all, while the documentation states it should add SSL_SERVER_CERT, SSL_CLIENT_CERT and SSL_CLIENT_CERT_CHAINn (with n = 0,1,2,..) as headers. Any ideas why this option is not working?
I then tried setting the headers myself using RequestHeader. This works fine for all variables except SSL_CLIENT_CERT_CHAIN. It shows null in the header. Any ideas why the certificate chain is not being filled?
This is my first Apache configuration:
