Section 8 - Security
Path: Security > Authentication > External Auth Server > LDAP Server
The LDAP authentication method uses LDAP to exchange authentication credentials between the router and an
external server. The LDAP server maintains a large database of users in a directory structure, so users with the
same user name but belonging to different groups can be authenticated since the user information is stored in
a hierarchal manner. Also of note is that configuring a LDAP server on Windows or Linux servers is considerably
less complex than setting up NT Domain or Active Directory servers for user authentication.
The details configured on the controller will be passed for authenticating the router and its hosts. The LDAP
attributes, domain name (DN), and in some cases the administrator account & password are key fields in allowing
the LDAP server to authenticate the controller.
To configure the router to connect to your LDAP server:
1. Click
