Authentication Server

Device supports user authentication against:
  • an LDAP Server
  • a RADIUS Server
  • an internal database defined in Device

User authentication can be performed using local user database, RADIUS, LDAP or any combination of these.

Local Authentication

Device provides a local database for storing user information. You can configure device to use this local database to authenticate users and control their access to the network. Choose local database authentication over LDAP or RADIUS when the number of users accessing the network is relatively small. Registering dozens of users takes time, although once the entries are in place they are not difficult to maintain. For networks with larger numbers of users, user authentication using LDAP or RADIUS servers can be more efficient.

Combination of external and local authentication is useful in large networks where it is required to provide guest user accounts for temporary access while a different authentication mechanism like RADIUS for VPN and SSL VPN users provides better security as password is not exchanged over the wire.

External Authentication

External Authentication Servers can be integrated with the device for providing secure access to the users of those servers.

To manage external authentication servers, go to System Management > System Settings > System > Authentication Server.
