I have CUCMBE 7.1 integrated to AD and have successfully sync CUCM users into LDAP from AD. However, Unity Connection doesn't see them to import if I go to TOOLS> IMPORT USERS> and Find End Users in UC. Is there anything else I need to do to import users into Unity Connection from CUCM BE?
Have you checked to make sure that all of your users in CUCM have a Primary Extension defined under the Directory Number Associations section of the End User page? You won't be able to import users into CUC until they have a primary extension.
