SonicWALL SSO Authentication Using the SSO Agent
For users on individual Windows workstations, the SSO Agent (on the SSO workstation)
handles the authentication requests from the SonicWALL appliance. There are six steps
involved in SonicWALL SSO authentication using the SSO Agent, as illustrated in the following
figure.
The SonicWALL SSO authentication process is initiated when user traffic passes through a
SonicWALL security appliance, for example, when a user accesses the Internet. The sent
packets are temporarily blocked and saved while the SonicWALL security appliance sends a
“User Name” request and workstation IP address to the authorization agent running the SSO
Agent (the SSO workstation).
The authorization agent running the SSO Agent provides the SonicWALL security appliance
with the username currently logged into the workstation. A User IP Table entry is created for
the logged in user, similarly to RADIUS and LDAP.
