Hmm. Reading the SSL man page more closely, you're right. This is a bug
IMHO --- the intention was that presence of a root.crt file would force
verification. What we wanted to do was to allow servers to operate
without a root.crt file if they didn't care about verifying client
certificates.
It looks like the original coder simply got this backwards: the backend
code doesn't set SSL_VERIFY_FAIL_IF_NO_PEER_CERT, but the frontend code
does, which is silly because the flag is ignored on the client side.
Does anyone see a reason not to turn on SSL_VERIFY_FAIL_IF_NO_PEER_CERT
on the backend side?
