Domain-based User Management
A domain is a group of users.
A NAS manages users based on domains. Each access user belongs to a domain that is determined by the user name provided for login, as shown in Figure 1-16.
Two default domains named default and default_admin are available on a device. They can be modified but not deleted.
The default domain is not used. The default_admin domain is used for administrators (logging in through SSH, Telnet, FTP, or console port). By default, local authentication is performed for administrators in this domain when the administrators log in without entering the domain name.
The preconfigured authentication, authorization, and accounting schemes are used in the corresponding domain view to implement authentication, authorization, and accounting for users. AAA provides the default schemes including local authentication, local authorization, and local accounting. If no authentication, authorization, or accounting scheme is applied to a domain, the default schemes are used for users in this domain.
Authorization information delivered by an AAA server is used preferentially because authorization information configured in a domain has a lower priority. When the AAA server does not have or does not support authorization, the authorization attributes configured in a domain take effect. In this manner, you can increase services flexibly by means of domain management, regardless of the authorization attributes provided by the AAA server.
