Chapter 3, Getting Started with FreeRADIUS, gives a brief introduction on the various components of FreeRADIUS. It also discusses the process of handling a basic authentication request.
Chapter 4, Authentication, teaches authentication methods and how they work. Extensible Authentication Protocol (EAP) is covered later in a dedicated chapter.
Chapter 5, Sources of Usernames and Passwords, covers various places where username/password combinations can be stored. It shows which modules are involved and how to configure FreeRADIUS to utilize these stores.
