http://nginx.org/r/ssl_client_certificate has slightly different
words for what it does. It also refers to the "ssl_verify_client" and
"ssl_trusted_certificate" directives.

Can you provide a config that shows the problem that you report?

From your description, only the ca cert needs to be in the file; but
I think that including the other certs should not break anything. Can
you tell, are there the expected newlines in the file, between the certs?
