User authentication through RADIUS servers (HNAS server only)
Remote Authentication Dial In User Service (RADIUS) is a networking
protocol that provides centralized authentication, authorization, and
accounting management for computers to connect and use a network service.
RADIUS is a client/server protocol that runs in the application layer, using
UDP as transport. The SMU acts as a RADIUS client component that
communicates with the RADIUS server to validate logins. The RADIUS server
is usually a background process running on a Unix or Microsoft Windows
server.
RADIUS serves three functions:
• Authenticates users or devices before granting them access to a network.
• Authorizes those users or devices for certain network services.
• Accounts for usage of those services.
The RADIUS server compatibility is as follows:
• For IPv4 only, works with FreeRADIUS 2.1 or Windows 2003 Internet
Authentication Service (IAS).
• For IPv6, requires FreeRADIUS 2.2 or Windows 2008 Network Policy
Server (NPS).
Configuring user authentication through a RADIUS server requires the
following:
• The RADIUS server must be set up and operational.
• The SMU must be able to communicate with the RADIUS server using the
network.
• You must know the RADIUS server's:
○ IP address or DNS name.
○ Authentication port.
○ Shared secret for the SMU.
You can specify and prioritize multiple RADIUS servers for authentication.
Note: The SMU contacts RADIUS servers in order of priority; the SMU will
always try to contact higher priority servers before lower priority servers, and
you cannot map SMU users to authenticate through a specific RADIUS server.
If you specify an incorrect secret or there are network problems that prevent
the SMU from communicating with the highest priority RADIUS server, the
SMU will try to contact the secondary RADIUS server, then the third RADIUS
