9.
The user inputs the password.
10.
After receiving the login password, the HWTACACS client sends the HWTACACS server a
continue-authentication packet that carries the login password.
11.
The HWTACACS server sends back an authentication response to indicate that the user has
passed authentication.
12.
The HWTACACS client sends the user authorization request packet to the HWTACACS server.
13.
The HWTACACS server sends back the authorization response, indicating that the user is now
authorized.
14.
Knowing that the user is now authorized, the HWTACACS client pushes its configuration interface
to the user.
15.
The HWTACACS client sends a start-accounting request to the HWTACACS server.
16.
The HWTACACS server sends back an accounting response, indicating that it has received the
start-accounting request.
17.
The user logs off.
18.
The HWTACACS client sends a stop-accounting request to the HWTACACS server.
19.
The HWTACACS server sends back a stop-accounting response, indicating that the
stop-accounting request has been received.
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

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.
