Hmm - I'm not sure if the override_cert_url = no code works
correctly - I seem to remember I had problems with it, but I just
set it to yes and forced the server anyway, as it seemed better
than trusting the client-provided cert (our setup is private CA,
so I know what the OCSP server is). I think I saw the same - that
it wouldn't extract the URL from the cert, and just came back with
(null)s. As usual, I just blamed OpenSSL and moved on.

If I get a chance, I'll try and check it again.

soft_fail will allow the auth to succeed in the event that there
is no response (rather than a negative response) from the OCSP
server - otherwise it "fails safe" and rejects the request. It's
in case the OCSP server happens to be down for some reason.

Always the right thing anyway :-)
