Overview

In CUCM, there are several primary user journeys for directory search:

• Cisco Jabber (soft clients)
• Corporate Directory IP Phone Service (physical phones)
• 3rd-Party Integrations, such as:
  • CUAC
  • Billing
• In CUCM 10.6 and 11.0, Jabber (when integrated using UDS) requires all users provisioned in all clusters, which is problematic as it introduces userid duplication during data syncs.
• The CUCM 11.5(1) LDAP Search feature supports seamless support multi-cluster directory search. This means the external directory is used with UCM acting as a UDS Proxy for directory Search requests.
  • LDAP Search may be mandated for customers deploying MRA (Mobile and Remote Access), as this is a required configuration to support directory search outside the Enterprise for several directory integrations.
