When I enter my authentication code and click on Validate, I got redirected back to the login page. Why is this happening?

It might be the case that the plugin is not able to write the PHP session info (into the /var/lib/php/sessions directory ) because of permission issues, and hence it is failing at the authentication step.
Please update to the latest plugin version (5.0.0) which has the bug fix for this.
