DX Auth showing views although not logged-in

[eluser]Mithun[/eluser]
Hi All,

I Have a problem with DX_Auth library, I have setup it, successfully able to log in and log out, change passwords etc, issue is with other controllers, whenever i tries to access any other controller method say <base_url>/opportunities/index.php i wss able to view it with out loggedin.
Do i need to check for log in like

Code:

if($this->dx_auth->is_logged_in())

in each controller or am I doing anything wrong?
