Login, Session, redirection, failure...

Did you define your base path this way?

Code:

$config['base_url']    = "https://www.your_domain.com";

I just ask because in an other thread the problem was
switching between http and https.

What you could try to do is storing the session vars in your database.
Just see what happens ..
