Lightweight Directory Access Protocol (LDAP)
LDAP is an application protocol for accessing and maintaining information services for the
distributed directory over an IP network. IP phones
can be configured to interface with a
corporate directory server that supports LDAP version 2 or 3. The following LDAP servers are
supported:

Microsoft Active Directory

Sun ONE Directory Server

Open LDAP Directory Server

Microsoft Active Directory Application Mode (ADAM)
The biggest plus for LDAP is that users can access the central LDAP directory of the corporation
using IP phones. Therefore they do not have to maintain the directory locally. Users can search
and dial out from the LDAP directory, and save LDAP entries to the local directory. LDAP entries
displayed on the IP phone are read only, which cannot be added, edited or deleted by users.
When an LDAP server is properly configured, the IP phone can look up entries from the LDAP
server in a wide variety of ways. The LDAP server indexes all the data in its entries, and “filters”
can be used to select the desired entry or group, and return the desired information.
Configurations on the IP phone limit the amount of the displayed entries when querying from
the LDAP server, and decide how attributes are displayed and sorted.
You can set a DSS key to be an LDAP DSS key, and then press the LDAP DSS key to enter the
LDAP search screen when the IP phone is idle.
