Passport Authentication System Not Working

I have an authentication system setup in my express node application, but I’ve been experiencing some errors with the passport authentication that I setup. For example, the registration system works fine, as does my validation system (which basically checks whether the user/pass combo is valid for my school’s grade book login). However, the actual passport login (which checks if the user/pass combo is a registered user in my mongoose database) is not functioning correctly.

Relavent part of app.js

//passport setup
app.use(passport.initialize());
app.use(passport.session());
passport.use(new LocalStrategy(function (username, password, done) {
User.findOne({username: username}, function (err, user) {
    user.checkLogin(password, function (error, userIsValid) {
        if (error) {
            console.log('Error:');
            return done(error);
        }
        if (userIsValid) {
            console.log('Valid:');

            areCredentialsValid(username, password, function (status) {
                if (status === true) {
                    return done(null, user);
                } else {
                    done(null, false, {message: 'Invalid login credentials'})
                }
            });
        }
    });
});
}));

user.js

 var mongoose = require('mongoose');
 var passportLocalMongoose = require('passport-local-mongoose');
 var Schema = mongoose.Schema;
 var bcrypt = require('bcrypt');

 var User = new Schema({
   username: String,
   password: String,
   studentID: {type: Number}
 });

 User.methods.checkLogin = function (password, callback) {
     bcrypt.compare(password, this.password, function (error, same) {
         if (error){
             callback(error);
         }
         callback(same);
     })
 };

   User.plugin(passportLocalMongoose);
   module.exports = mongoose.model('User', User);

and finally, index.js

var express = require('express');
var router = express.Router();
var passport = require('passport');
var User = require('../models/user');
var request = require('request');
var cheerio = require('cheerio');

//register
router.post('/register', function(req, res){
    var username = req.body.username;
    var password = req.body.password;
    var studentID = req.body.studentID;

    areCredentialsValid(username, password, function (statusBoolean) {
        if (statusBoolean === true){
            User.register(new User({
                username: username,
                password: password,
                studentID: studentID
            }), password, function (){
                console.log('Registered:');
                res.redirect('./');
                res.end()
            })
        }else{
            console.log('Invalid Credentials:');
            res.redirect('./');
            res.end()
        }
    });
});

function areCredentialsValid(username, password, callback){
    if (typeof username !== 'undefined' && username !== null && username !== '' &&
    typeof password !== 'undefined' && password !== null && password !== ''){
        var cookie = {};
        var responseBoolean = false;
        var config = {
        method: 'GET',
        url: 'https://parents.mtsd.k12.nj.us/genesis/j_security_check',

        }
        };
        request(config, function (error, response, body) {
        cookie = response.headers['set-cookie'];
        console.log(cookie);
        var config = {
            method: 'POST',
            url: 'https://parents.mtsd.k12.nj.us/genesis/j_security_check',
            form: {
                'j_username': username,
                'j_password': password
            },
            headers: {
                'Cookie': cookie,
                'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',

            }
        };
        request(config, function (error, response2, body) {
            //console.log(response);
            console.log(response2.headers);
          if (response2.headers['location'] === '/genesis/parents?gohome=true'){
              responseBoolean = true;
          }else{
              responseBoolean = false;
          }
          callback(responseBoolean);
          return responseBoolean;
            })
        })
    }
}

//login
router.post('/login', function(req, res) {

passport.authenticate('local', function (error, user, info){
    if (user === false) {
        // handle login error ...
    } else {
        // handle successful login ...
        }
    });
});

module.exports = router;

All help is appreciated. If its easier to deal with, the source code can be found here.
