An enterprise directory refers to an external Lightweight Directory Access Protocol (LDAP) directory server, such as OpenLDAP or Microsoft Active Directory Domain Services (AD DS). In AE Services, TSAPI, JTAPI, and DMCC services can use an LDAP directory for authentication purposes.

If you want to use an external LDAP directory for TSAPI, JTAPI, and DMCC services and you do not plan to use Microsoft AD DS Services with Kerberos for authentication, you must configure enterprise directory settings using the AE Services management console.

The enterprise directory settings may apply to the AE Services implementation for Microsoft Lync Server 2010 and 2013. If you administer AE Services for the integration with Microsoft Lync Server, see Deploying Avaya Aura® Application Enablement Services for Microsoft® products.
