How to cross verify user credential in MVC3& redirect to respective view,page not from DB

Hii to all,
I have a requirement that i need to create a simple Login Page,where i need to cross verify three types of Credentials i.e(Employee,Manager,Administrator)If username is employee i need to redirect to Employees's view's page,If username is Manager i need to redirect to Manager view page,If username is Administrator i need to redirect to Administrator view page.But here i dont have any database,i need to verify from frontend only.Please tell me is there any possibility for verifing it from controller or Model? and should i need to create three different views pages,three Controllers for three different types of users.In ASp.Net we use Responce.Redirect() for redirecting to required page,In MVC3 what is the code for redirecting to other view page.Can anyone help me with the code.Thanks in advance

Thanks
