How Does RADIUS Accounting for Single-Sign-On Work?

RADIUS Accounting is specified by RFC 2866 as a mechanism for a network access server (NAS) to send user login session accounting messages to an accounting server. These messages are sent at user login and logoff. Optionally, they can also be sent periodically during the user’s session.

When a customer uses an external or third-party network access appliance to perform user authentication (typically for remote or wireless access) and the appliance supports RADIUS accounting, a SonicWall network security appliance can act as the RADIUS Accounting Server, and can use RADIUS Accounting messages sent from the customer's network access server for single sign-on (SSO) in the network.

A SonicWallSMA 1000 Series appliance running SMA 12 or higher can be configured as an external RADIUS Accounting client, with the SonicWall network security appliance as the RADIUS Accounting server.

When a remote user connects through a SonicWall Secure Mobile Access or third-party appliance, the SMA or third-party appliance sends an accounting message to the SonicWall network security appliance (configured as a RADIUS accounting server). The SonicWall network security appliance adds the user to its internal database of logged in users based on the information in the accounting message.

When the user logs out, the SonicWall SMA or third-party appliance sends another accounting message to the SonicWall network security appliance, which then logs the user out.

When a network access server (NAS) sends RADIUS accounting messages, it does not require the user to be authenticated by RADIUS. The NAS can send RADIUS accounting messages even when the third-party appliance is using LDAP, its local database, or any other mechanism to authenticate users.

RADIUS accounting messages are not encrypted. RADIUS accounting is inherently secure against spoofing because it uses a request authenticator and a shared secret. RADIUS accounting requires that a list of the network access servers (NASs), that can send RADIUS Accounting messages, be configured on the appliance. This configuration supplies the IP address and shared secret for each NAS.
