ACK, but CURLOPT_SSL_VERIFYHOST should be set to 2 (certificate must
contain a cname and must match, the default) instead of 1 (certificate
must contain a cname, but must not match) when no_verify=0, see
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTSSLVERIFYHOST

curl_easy_setopt(ctx->curl_handle, CURLOPT_SSL_VERIFYHOST, noVerify ? 0 : 2);
