Prerequisites for Configuring Authorization
Before configuring authorization using named method lists, you must first perform the following tasks:
Enable authentication, authorization, and accounting (AAA) on your network access server.
Configure AAA authentication. Authorization generally takes place after authentication and relies on authentication to work properly. For more information about AAA authentication, refer to the “Configuring Authentication” module.
Define the characteristics of your RADIUS or TACACS+ security server if you are issuing RADIUS or TACACS+ authorization. For more information about configuring your Cisco network access server to communicate with your RADIUS security server, refer to the chapter “Configuring RADIUS”. For more information about configuring your Cisco network access server to communicate with your TACACS+ security server, refer to the “Configuring TACACS+” module.
Define the rights associated with specific users by using the username command if you are issuing local authorization.
