The VCS can be configured to use a database on an LDAP Directory Server to store 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 specification describes the schemas which are required to be installed on the
LDAP server:
