D-Link DWC-1000 User Manual224Section 6 - Securing Your NetworkConfigure LDAP ServerPath: Security > Authentication > External Auth Server > LDAP ServerThe LDAP authentication method uses LDAP to exchange authentication credentials between the controllerand external server. The LDAP server maintains a large database of users in a directory structure, so users withthe same username but belonging to different groups can be authenticated since the user information is storedin a hierarchal manner. Note that configuring a LDAP server on Windows or Linux servers is considerably lesscomplex than setting up NT Domain or Active Directory servers for user authentication.The details configured on the controller will be passed for authenticating the controller and its hosts. The LDAPattributes, domain name (DN), and in some cases the administrator account & password are key fields in allowingthe LDAP server to authenticate the controller.To configure your LDAP Server:1. Go to Security > Authentication > External Auth Server > LDAP Server tab.2. Complete the fields given in the table on the next page, and click Save.
