Domain-based User Management

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 1-26.

Figure 1-26  Using the user name to determine the domain

The device has two default domains: default (global default domain for common access users) and default_admin (global default domain for the administrator). The two domains can be modified but not deleted. If the domain of an access user cannot be obtained, the default domain is used.
  • The default domain is used for access users (users who use NAC for authentication). By default, local authentication is performed for users in this domain.
  • The default_admin domain is used for administrators (logging in through HTTP, SSH, Telnet, FTP, or console port). By default, local authentication is performed for users in this domain.

A user-defined domain can be configured as a global default domain for common access users and administrators.

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 scheme including local authentication, local authorization, and non-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.
