so i have to make a statis class in model directory wich is it cheks if usersname and password and validation, and then in the Controller a class with loginAction methode wich it checks if a user already logdin or not and then it redirects to View.

is this right Construction?

I also want to use Zend_Acl, becouse i wil have a diferent kind of users with difrent privleges, like admin , memeber , quest.

But how do i connect this two components with each other?
