Different users with differents privileges

Hi I’m pretty new with Nagios, and i’m trying to set up two differents users with different privileges. I mean when you log in to see the interface in the web deppending on wich user and password you enter you’ll see differents host.
Is that possible? Can anyone help me with it?
thanks guys
