LDAP

Based on TCP/IP, the Lightweight Directory Access Protocol (LDAP) provides standard multi-platform

directory service. It is developed on the basis of the X.500 protocol, and improves the read/write

interactive access, and browse and search functions of X.500. It is suitable for storing data that are not

often changed.
LDAP is typically used to store user information in a system. For example, Active Directory Server is used
in Microsoft Windows operating systems to store the user information and user group information for

authentication and authorization at login.

LDAP directory service

LDAP uses directories to maintain the organization information, personnel information and resource

information. The directories are organized in a tree structure and comprise entries. An entry is a set of
attributes with distinguished names (DNs).
The LDAP directory service is based on a client/server model, and all directory information is stored in

the LDAP server. Commonly used LDAP server products include Microsoft Active Directory Server, IBM

Tivoli Directory Server, and Sun ONE Directory Server.

LDAP authentication and authorization

IMPORTANT:

The device does not support LDAP authorization. You can configure an HWTACACS authorization
scheme to work with LDAP authentication. For more information about HWTACACS authorization scheme

configuration, see "

Configuring HWTACACS schemes

."

LDAP defines a set of operations to implement its functions. The main operations for authentication and

authorization are the bind operation and search operation:

The bind operation allows an LDAP client to establish a connection with the LDAP server, obtain the

access rights to the LDAP server, and check the validity of user information.
