• Directory Service (LDAP/AD)
LDAP (Lightweight Directory Access Protocol)/AD (Active Directory) is a directory service that is
both a directory and a protocol for controlling access to a network. The directory consists of a
database specialized for fast information retrieval and filtering activities. You create and store
user profile and login information on the external server.
•RADIUS
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used
to authenticate users by means of an external or built-in RADIUS server. RADIUS authentication
allows you to validate a large number of users from a central location.
Directory Structure
The directory entries are arranged in a hierarchical order much like a tree structure. Normally, the
directory structure reflects the geographical or organizational boundaries. The following figure
shows a basic directory structure branching from countries to organizations to organizational units
to individuals.

Distinguished Name (DN)
A DN uniquely identifies an entry in a directory. A DN consists of attribute-value pairs separated by
commas. The leftmost attribute is the Relative Distinguished Name (RDN). This provides a unique
name for entries that have the same “parent DN” (“cn=domain1.com, ou=Sales, o=MyCompany” in
the following examples).
cn=domain1.com, ou = Sales, o=MyCompany, c=US
cn=domain1.com, ou = Sales, o=MyCompany, c=JP
Base DN
A base DN specifies a directory. A base DN usually contains information such as the name of an
organization, a domain name and/or country. For example, o=MyCompany, c=UK where o means
organization and c means country.
