nodejs + passport + express 3.0 + connect-flash no flashing?
===

I'm using a passport-local strategy for authenticate users. I followed the guide given by Jared Hanson and installed connect-flash in order to give flash method to the req object. So one of my request handlers is the following:

     app.post('/login',                             
          passport.authenticate('local', {           
              successRedirect: '/'                   
            , failureRedirect: '/login'              
            , successFlash: 'Bienvenido'             
            , failureFlash: 'Credenciales no válidas'                             
          })                                         
      );   


When the user login fails, it redirects the user to /login again but it doesnt flash anything :/
