Need to retrieve form data - node.js

Question

I have some login page, as soon as the authenticated get success, in the next page, I should display Login Details.. ( ie., username and password )
I'm using Express NodeJs, Passport, connect-flash, mongoose
My prob is: I'm unable to understand how to retrieve username, password in the next rendered page..
Please someone suggest me how to achieve it. I'm not asking you code, BUT show me a way to get my output.
EDIT:
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'm trying to display username which I entered in the login page.. I'm getting output: undefined
please tell me what went wrong and what I need to correct?

In the most general sense, if authentication succeeds the user object you return from authenticate ends up at req.user in your downstream functions.
http://passportjs.org/guide/authenticate/
And then, assuming you are using sessions, any subsequent requests will also expose req.user based on your serializeUser/deserializeUser functions.
