Node.JS + HTTPS + Client Cert = Problems

I've been trying to get Node.JS to work with SSL and client certificates. Originally, I had tried to get it to work with restify (see my question here). When I couldn't get that to work, I backed up and tried to find an example that illustrated what I was trying to accomplish. I tried this one, and I'm receiving an odd error.

Code is as follows:

Server:

var sys = require("sys");
var fs = require("fs");
var https = require("https");

var options = {
  key: fs.readFileSync("../certs/server.key"),
  cert: fs.readFileSync("../certs/server.crt"),
  ca: fs.readFileSync("../certs/ca.crt"),
  requestCert: true,
  rejectUnauthorized: true
};

https.createServer(options, function (req, res) {
  console.log(req);
  res.writeHead(200);
  sys.puts("request from: " + req.connection.getPeerCertificate().subject.CN);
  res.end("Hello World, " + req.connection.getPeerCertificate().subject.CN + "\n");
}).listen(8080);

sys.puts("server started");

Client:

var https = require('https');
var fs = require("fs");

var options = {
    host: 'localhost',
    port: 8080,
    path: '/hello',
    method: 'GET',
    key: fs.readFileSync("../certs/user.key"),
    cert: fs.readFileSync("../certs/user.crt"),
    ca: fs.readFileSync("../certs/ca.crt"),
    passphrase: 'thepassphrase'
};

var req = https.request(options, function(res) {
    console.log("statusCode: ", res.statusCode);
    console.log("headers: ", res.headers);

    res.on('data', function(d) {
        process.stdout.write(d);
    });
});

req.end();

req.on('error', function(e) {
    console.error(e);
});

Running test-client.js yields this:

{ [Error: socket hang up] code: 'ECONNRESET' }

Attempting the same sort of thing with curl:

curl -k -v --key user.key --cert user.crt:thepassphrase --cacert ca.crt https://localhost:8080/hello

yields:

* About to connect() to localhost port 8080 (#0)
*   Trying 127.0.0.1... connected
* successfully set certificate verify locations:
*   CAfile: ca.crt
  CApath: /etc/ssl/certs

curl: (35) Unknown SSL protocol error in connection to localhost:8080

If I want to go the extra step to require a client certificate, how would I go about it?
