Answer 1

looks like you've set the callback URL to http://yourdomain.com/callback in your salesforce oauth app, but have not define a handler for it correctly
either change the callback URL of your salesforce oauth app to
http://yourdomain.com/auth/forcedotcom/callback
or change the following in your code
app.get('/auth/forcedotcom/callback', passport.authenticate('...
to
app.get('/callback', passport.authenticate('forcedotcom', {
successRedirect: '/',
failureRedirect: '/login'
}), function(req, res) {
res.redirect('/');
});
