Section 8 - Security AD Server Path: Security > Authentication > External Auth Server > AD Server Active Directory authentication is an enhanced version of NT Domain authentication. The Kerberos protocol is leveraged for authentication of users, who are grouped in Organizational Units (OUs). In particular the Active Directory server can support more than a million users given is structure while the NT Domain server is limited to thousands. The configured Authentication Servers and Active Directory domain(s) are used to validate the user with the directory of users on the external Windows based server. This authentication option is common for SSL VPN client users and is also useful for IPsec / PPTP / L2TP client authentication. To configure the router to connect to your AD server: 1. Click Security > Authentication > External Auth Server > AD Server tab. 2. Complete the AD server information from the table on the next page and click Save. You can configure up to three servers.
