how do I implement role based access control in firebase

Question

This is my first foray into Firebase & nosql, I come from a SQL background.

Using Simple Login Security Email/Password, how do I limit access to data in Firebase? For example, some user will have access to create a business object (users, customers, categories, etc), others won't. Is there a way to attach a list of permissions to the "auth" variable?
