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.
