Authentication vs. Authorization
Authentication is the process of verifying that a user is who he says he is.
Once a user is authenticated, the user's group is used to determine his
system and port permissions. The user's assigned privileges determine
what type of access is allowed. This is called authorization.
When Dominion KX II is configured for remote authentication, the
external authentication server is used primarily for the purposes of
authentication, not authorization.
The flow diagram illustrates this process:
