In the words of Montoya, "I do not think it means what you think it
means", referring to "ssl_ca".  That file is not used to to establish
the trust chain to your server certificate, but rather, to your client's
certificates (e.g. if you run a local CA to issue user certificate
for mutual authentication, you would put your local CA certificate here).

(Maybe this config variable should be renamed "ssl_client_ca".)

Appending intermediate and server certificates is what you're supposed
to do.
