Apache 2 authentication error

Question

Attempting to implement client authentication with an SSL cert, according to this HOWTO, I receive the following errors.

Apache:

Re-negotiation handshake failed: Not accepted by client!?

Firefox:

ssl_error_handshake_failure_alert

I assume it is a configuration error, but have not been able to locate it.

Additional info:
Commercial CA server cert servers secure works without problem in Apache 2.2 & Passenger. Only client authentication related directives do not work.

Answer 1

Is your certificate signed by verizon or someone like that? If not, you might want to add an exception in firefox. By default it stops you.

pd. doesn't sound like a passenger question

Answer 2

When you require client certificate authorization, you have to point Apache to file containing the root CA (and intermediates also) certificates which issued the client certificate

Also post your client authentication config part.
