The VCS can be configured to use a database on an LDAP Directory Server to store device
authentication credential information (usernames, passwords, and other relevant information).
This section describes how to download the schemas that must be installed on the LDAP server,
and how to install and configure two common types of LDAP servers, Microsoft Active Directory and
OpenLDAP, for use with the VCS.

About the LDAP databases

The following ITU specifications describe the schemas which are required to be installed on the
LDAP server:

H.350

Directory services architecture for multimedia conferencing - an LDAP schema to
represent endpoints on the network.

H.350.1 Directory services architecture for H.323 - an LDAP schema to represent H.323

endpoints.

H.350.2 Directory services architecture for H.235 - an LDAP schema to represent H.235

elements.

H.350.4 Directory services architecture for SIP - an LDAP schema to represent SIP endpoints.

The schemas can be downloaded in

ldif format from the web interface on the VCS. To do this:

1. Go to VCS configuration > Authentication > Devices > LDAP Schemas. You are presented with

a list of downloadable schemas.

2. Click on the Download button next to each file to open it.
3. Use your browser's Save As command to store it on your file system.

Downloading the H.350 schemas

Prerequisites

These step-by-step instructions assume that Active Directory has already been installed. For details
on installing Active Directory please consult your Windows documentation.
The following instructions are for Windows Server 2003 Enterprise Edition. If you are not using this
version of Windows, your instructions may vary.

Installing the H.350 schemas

After you have

downloaded the H.350 schemas

, install them as follows:

Open a command prompt and for each file execute the following command:
ldifde -i -c DC=X <ldap _ base> -f filename.ldf
where:
<ldap _ base> is the base DN for your Active Directory server.

Microsoft Active Directory
