Domain-based user management

NAS devices manage users based on Internet service provider (ISP) domains. An ISP domain supports a
collection of users.
On a NAS, each user belongs to one ISP domain. A NAS determines the ISP domain a user belongs to
by the username entered by the user at login, as shown in
Figure 7 Determine the ISP domain of a user by the username
A user enters the username in
the form of
userid@domain-name
The authentication, authorization, and accounting of a user depends on the AAA methods configured for
the domain that the user belongs to. If no specific AAA methods are configured for the domain, the
default methods are used. By default, a domain uses local authentication, local authorization, and local
accounting.
The AAA feature allows you to manage users based on their access types:
LAN—LAN users must pass 802.1X authentication or MAC address authentication to access the
•
network.
Login—Login users include SSH, Telnet, FTP, and terminal users who log in to the device.
