Middleware in Node.js with OO JavaScript

Currently I am trying to use the middleware "passport" in an object oriented Node.js server. After restarting the server everything works fine. I can access the route where no authentication is required. But when I am trying to access a route with authentication I always get the response 401 (No-Authentication). This seems to be ok but unfortunately I do not enter the function(username, password, done) in the LocalStrategy.

So I think my problem is in the way I try to use a middleware in the oo javascript style. The template I used to start is from the RedHat OpenShift Cloud and can be seen in: https://github.com/openshift/nodejs-custom-version-openshift/blob/master/server.js

Here is my server initialization method where I tried to use the passport middleware:

self.initializeServer = function() {

    self.createGetRoutes();
    self.createPostRoutes();

    self.app = express.create();

    passport.use(new LocalStrategy(
        function(username, password, done) {
            console.log("TEST");

            process.nextTick(function () {
                console.log('Here I am!');
                return done(null, user);
            });
        }
    ));

    self.app.configure(function() {
        self.app.use(passport.initialize());
    });

    // Paths without authentication
    self.app.get('/holy', function(req, res) {res.send('SHIT! \n')});

    //  Add GET handlers for the app with authentication (from the getRoutes).
    for (var g in self.getRoutes) {
        self.app.get(g, passport.authenticate('local', { session: false }), self.getRoutes[g]);
    }

    // Add POST handlers for the app with authentication (from the postRoutes).
    for (var p in self.postRoutes) {
        self.app.post(p, passport.authenticate('local', { session: false }), self.postRoutes[p]);
    }
};
