Hey Steele, check out this branch of Passport:

https://github.com/jaredhanson/passport/tree/flatiron

I am currently using the two together, however, this is only for plain authentication. I have yet to try the oAuth, but I dont see any reason why it would not work.

However, just keep in mind that you will have to use a few tricks as Jared mentioned above to get it working. Here are the relevant snippets from my code:

// User is a flatiron/Resourceful model factory here. The set up of this is not shown below.
u = User.new(
    {
        "username": "test_user",
        "password": "secret",
        "email": "[email protected]"
    }
);

u.save();

function findByUsername(username, done) {
  User.find({"username":username}, function(err, user) {
    if (err) {
        return done(err, null);
    }
    else if (user) {
        return done(null, user[0]);
    }
    else {
        return done(null, null);
    }
  });
}

passport.use(new LocalStrategy(
  function(username, password, done) {
    // asynchronous verification, for effect...
    process.nextTick(function () {

      // Find the user by username.  If there is no user with the given
      // username, or the password is not correct, set the user to `false` to
      // indicate failure and set a flash message.  Otherwise, return the
      // authenticated `user`.
      findByUsername(username, function(err, user) {
        if (err) { return done(err); }
        if (!user) { return done(null, false, { message: 'Unkown user ' + username }); }
        debugger;
        console.log(password);
        console.log(user.password);
        if (user.password != password) { return done(null, false, { message: 'Invalid password' }); }
        return done(null, user);
      })
    });
  }
));


passport.serializeUser(function(user, done) {
  done(null, user.username);
});

passport.deserializeUser(function(username, done) {
  findByUsername(username, function (err, user) {
    done(err, user);
  });
});

App.router.path('/', function() {
    this.post('/login',
        function() {
            self = this;
            function next() {
                console.log('next wrap');
                self.res.emit('next');
            }
            passport.authenticate('local', function(err, user) {
                console.log(user);
                if (err) { self.res.end("SERVER ERROR\n") }
                if (!user) { self.res.end("false") }
                else {
                    self.req.logIn(user, function(err) {
                        if (err) {throw err}
                        self.res.writeHead(200, {'Content-Type': 'text/html',
                            'Authentication': JSON.stringify(self.req._passport.session)});
                        self.res.end("true");
                    });

                }
            })(this.req, this.res, next);
        }
    );
});

I believe I got this working with a simple package.

https://npmjs.org/package/flatiron-passport
https://github.com/travist/flatiron-passport

Please read the README.md on how to use. For the most part, it is a pretty simple wrapper around passport that makes it work within flatiron. I have only so far tested LocalStrategy, but it should work with others since I basically maintained the API between the two. Please test this and let me know if this works for you guys.

Hi,

I'm having some trouble the debugger says that "req" has no method "isAuthenticated". I'm checking if the user is authenticated in the before hook to not go all the way up to the app's router. What do you think that the problem might be.

app.use(flatiron.plugins.http, {
  before : [
    function(req, res) {
      req.originalUrl = req.url;
      res.emit('next');
    },
    connect.cookieParser(),
    connect.session({ secret : 'keyboard cat' }),
    passport.initialize(),
    passport.session(),
    function(req, res) {

      if (!/^\/dashboard$|dashboard\/.*$/.test(req.url)) {
        return res.emit('next');
      }

      if (req.isAuthenticated()) {
        return res.emit('next');
      }

      res.redirect('/');
    },
    ecstatic(path.join(__dirname, './public'), {
      autoIndex : false,
      cache : "0, no-cache, no-store, must-revalidate"
    }) //cache control was turned off
  ]
});

Robert.
