title: How and where RADIUS and EAP combine?
body: <p>I have been reading a little bit about authentication methods.
  I have read about RADIUS and about EAP.
  I just don't understand the connection between them.</p>
  
  <p>RADIUS is a authentication protocol which uses shared secret and other methods to make a safe authentication, and EAP is more of a generic protocol. I know that EAP doesn't do anything on its own (that it's just a framework), and and a more specific type (like EAP-TLS) is used to perform the authentication.</p>
  
  <p>I just don't understand if a authentication process with a client -> authenticator -> authentication server, is supposed to pick one of the protocols or if they are somehow combined.</p>
  
  <p>I am sure I am just getting it completely wrong and would like if someone just briefly explain what I am missing.</p>
  
  <p>Thank you!</p>
