Single Sign-On using a FortiAuthenticator unit

Configuring the FortiAuthenticator unit

The FortiAuthenticator unit can poll FortiGate units, Windows Active Directory, RADIUS servers, LDAP servers, and FortiClients for information about user logon activity.

To configure FortiAuthenticator polling:

  1. Go to Fortinet SSO Methods > SSO > General.
  2. In the FortiGate section, leave the Listening port at 8000, unless your network requires you to change this. The FortiGate unit must allow traffic on this port to pass through the firewall.

Optionally, you can set the Login Expiry time. This is the length of time users can remain logged in before the system logs them off automatically. The default is 480 minutes (8 hours).

  1. Select Enable Authentication and enter the Secret key. Be sure to use the same secret key when configuring the FSSO Agent on FortiGate units.
  2. In the Fortinet Single Sign-On (FSSO) section, enter
Enable Windows Active Directory domain controllers Select for integration with Windows Active Directory.
Enable Radius accounting SSO clients Select if you want to use a Remote Radius server.
Enable Syslog SSO Select for integration with Syslog server.
Enable FortiClient SSO Mobility Agent service

Enable Authentication

Select both options to enable single sign-on by clients running FortiClient Endpoint Security. Enter the Secret key. Be sure to use the same secret key in the FortiClient Single Sign-On Mobility Agent settings.
  1. Select OK.

For more information, see the FortiAuthenticator Administration Guide.
