Get Entered Data after authentication success

Iam using Express NodeJs, Passport, connect-flash, mongoose

My prob is: Iam unable to understand how to retreive username, password in the next rendered page.

Please someone suggest me on how to achieve this..

app.js

var http = require('http');
var express =  require('express'),
    passport = require('passport')
    , LocalStrategy = require('passport-local').Strategy,
    flash = require('connect-flash'),
    User = require('./routes/userdao.js');


passport.use(new LocalStrategy(
    function(username, password, done) {
        User.findOne({ uname: username ,pwd:password}, function(err, user) {
            if (err) { return done(err); }
            if (!user) {
                return done(null, false, { message: 'Incorrect username.' });
            }
            return done(null, user);
        });
    }
));


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

passport.deserializeUser(function(id, done) {
    User.findById(id, function(err, user) {
        done(err, user);
    });
});


var app = express();


app.configure(function(){
    app.use(express.logger('dev'));     /* 'default', 'short', 'tiny', 'dev' */
    app.use(express.cookieParser());
    app.use(express.bodyParser());
    app.use(express.session({ secret: 'mysecret' }));
    app.use(flash());
    app.use(passport.initialize());
    app.use(passport.session());
    app.engine('.html', require('ejs').__express);
    app.set('view engine', 'html');
    app.set('views', __dirname + '/views');
    app.use(app.router);
    // app.use(express.errorHandler());

}).listen(3000);

console.log('Listening on port 3000...');
app.get('/',function(req,res){
  /*  req.flash('info', 'Flash is back!')
    res.redirect('/success');*/
    res.render('home.ejs');
});

app.get('/login',function(req,res){
    res.render('login.ejs');
});

app.get('/success',function(req,res){
    res.render('success.ejs',{ uname : req.user.username }); 
});

app.post('/login',
    passport.authenticate('local', { successRedirect: '/success', failureRedirect: '/login',
        failureFlash: true  }));

success.ejs

<%= uname %> // I WANT TO RETREIVE USERNAME HERE WHICH WAS ENTERED IN LOGIN PAGE..

When your passport.deserializeUser returns the user data, passport populates req.user object with it. You will need to pass this object to the template as a second param of the res.render method, in your route handler:

app.js

(...)
app.get('/success', function(req, res, next){
    res.render('user', { user: req.user })
});

success.ejs

<%= user.uname %>
