LDAP Interface
Directory information can be transferred using the LDAP protocol. A central service 
(LDAP server) manages a comprehensive, hierarchically organised directory which 
can be queried by an LDAP client via LDAP. The OpenCom 100 communications 
system supports two different LDAP applications:
• OpenCom 100 communications system as LDAP client: an external directory can 
be queried via LDAP, for example, in order to display the information thus 
gathered when there is a call. 
• OpenCom 100 communications system as LDAP server: the telephone book 
managed by the OpenCom 100 communications system can be accessed via 
LDAP. 
Address Queries using LDAP
You can search the data of the central telephone book of the OpenCom 100 from a 
workstation computer in the LAN using LDAP (Lightweight Directory Access Protocol). 
When configuring an LDAP-enabled programme, specify the IP address of the 
OpenCom 100 as the address of the LDAP server.
LDAP with Outlook Express / Windows Mail
You can configure and operate the LDAP directory service with “Outlook Express” or 
“Windows Mail”, an e-mail programme, as follows:
1. Call up the Accounts command in the To ol s menu.
The Internet Accounts dialogue box will then open.
2. Click on Add. Select the Directory Service command from the pop-up menu.
3. Under Internet directory (LDAP) server, enter the address of the 
OpenCom 100. It is not necessary to enter log-in data to query the central tele-
phone book. You have to enter the log-in data for the account on the 
OpenCom 100 communications system here if you wish to also query entries from 
the central telephone book or from the company telephone book additionally. 
Click twice on Next. Then click on Finish.
4. Check the function. In the Edit menu, call up the Find: People command.
The Find: People dialogue box will then open.
