So I've got my ssl client working pretty well. It does great with most
websites, but some of them it doesn't verify the certificate chain for,
returning the above error. The CA root cert in question is in the
certificate store, and the server isn't actually sending the root so I'm
pretty sure that openssl has even found it in the store and is trying to
verify it. I've pasted the details below of a certificate that is working
(Equifax) and one that isn't (Verisign). The only clue that I have is
that the Verisign cert doesn't have any extensions on it. Maybe by default
the openssl library is requiring the cert to be configured to be able to
sign other certs? If this is true, what can I do? Any guidance or ideas
appreciated. I'm not sure what to do next.
