OCSP_basic_verify:signer certificate not found with my own ocsp responder

Question

I'am developing my own OCSP responder.

First, I just want to send an OCSP request with openssl to my responder and receive a correct answer.

I have a CA certificate CA.crt and its son RC.crt. I want to check status certificate of RC.crt.

My responder signs the response with its own self-signed certificate (OCSPSigning key usage...) caOcsp.pem. (In RFC2560 it is written "The key used to sign the response must belong to one of the following... A trusted Responder whose public key is trusted by the requester ...

So I just do :

openssl ocsp -issuer CA.crt -CAfile ..\caOcsp.pem -VAfile ..\caOcsp.pem -cert RC.crt -req_text -url http://localhost:8080/myServlet

In openssl documentation :

-CAfile file containing trusted certificate there are **used to verify the signature on the ocsp response**  (That's why I put my ocsp certificate)
-VAfile file **containing explicitly trusted responder certificate**  (That's why I put my ocsp certificate too...)

and I got the following response :

What have I forgotten? What is wrong?

Answer 1

In my server application I built my OCSPRespBuilder with the right certificate but my responderID used to create this OCSPRespBuilder was wrong.

Now It works.
