Authentication determines if the provided user credentials (username/password) are correct. If authentication succeeds, the user is logged in.

Authorization determines what operations the user can perform after login. Authorization can be for no access, read access, or read and write access.

In the Access Control page, the type of Authentication and Authorization can be defined. AAA servers are defined in this page.

This module guides account management administrators to manage AAA servers, user accounts, and user roles. It provides the functionality required to manage all aspects of user accounts.
