5 LDAP
LDAP is a vendor-independent protocol standard used for accessing, querying and updating a directory
using TCP/IP. Based on the X.500 Directory Services model, LDAP is a global directory structure that
supports strong security features including authentication, privacy and integrity.
NOTE: The LDAP feature is only available for the 3108 and 3216 switch models.
If individual user accounts are stored on an LDAP-enabled directory service such as Active Directory, you
can use the directory service to authenticate users. The default values given for the LDAP search and
query parameters are defined for use with Active Directory.
The settings made in the OBWI let you configure your authentication configuration parameters. The
software sends the username, password and other information to the appliance, which then determines
whether the user has permission to view or change configuration parameters for the appliance in the
OBWI.
NOTE: Unless otherwise specified, the LDAP default values should be used unless Active Directory has
been reconfigured. Modifying the default values can cause LDAP authentication server communication
errors.
5.1 Configuring LDAP in the User Interface
5.1.1 LDAP Overview parameters
On the LDAP Overview window in the OBWI, you can configure the LDAP authentication priority and the
parameters that define LDAP server connection information.
LDAP authentication priority
In the LDAP Priority section of the OBWI, you can disable LDAP or you can set the authentication priority
by choosing whether local authentication or LDAP authentication should happen first.
To configure LDAP authentication priority parameters:
1. Select A p p lian ce - A p p lian ce Settin g s - User Accou n ts - L DA P A ccou n ts - O v erview.
2. Select either LDAP Disab led , LDAP b efore Local or LDA P after Local for the LDAP Priority.
3. Click S av e.
LDAP servers
The Address fields specify the host filenames or IP addresses of the primary and secondary LDAP servers.
The secondary LDAP server is optional.
The Port fields specify the User Datagram Protocol (UDP) port numbers that communicate with the LDAP
servers. The default value is 389 for non-secure LDAP and 636 for secure LDAP (LDAPS). The default
Port ID is automatically entered by the software when an access type is specified.
The Access Type radio buttons specify how a query is sent to each LDAP target device. When using
LDAP, all usernames, passwords and other information sent between an appliance and an LDAP server are
sent as non-secure clear text. Use LDAPS for secure encrypted communication between an appliance
and an LDAP server.
To configure LDAP server parameters:
1. Select A p p lian ce - A p p lian ce Settin g s - User Accou n ts - L DA P A ccou n ts - O v erview.
