What am I doing wrong? Whenever POST /login is hit, it just hangs...

auth.js

// routes/auth.js

var passport = require('passport')
  , LocalStrategy = require('passport-local').Strategy;


exports.member_auth = function(req, res) {
  // console.log("Request Body == ", req.body);
  var strategy = new LocalStrategy({
    usernameField: 'email',
    passwordField: 'password'
  },
  function(username, password, done) {
    console.log("username: " + username);
    console.log("password: " + password);
    return done(null, false);
    // when this route is hit, it just hangs, despite returning done(null, false)
  });

  passport.use(strategy, function(username, password, done){
    // silence is golden
  });

  passport.authenticate('local'); 
}

index.js

// routes/index.js

var auth = require('./auth');

exports.set = function(app, express) {
  app.post('/login', auth.member_auth);
  // when this route is hit, it just hangs, despite returning done(null, false)
}
