/mcpUsers page in Unity Connection Administration to manually refresh information from Cisco Unified CM for voicemail users that were created using the Import Users page. Considerations While Importing Data From LDAP Directory Integrated with Cisco Unified CM An alternative of creating users by importing data from Cisco Unified Communications Manager is to integrate Unity Connection with an LDAP directory and then import user data from the LDAP directory as described in the LDAP, on page 147 chapter. Note the following: • If you import users from Cisco Unified CM and if Cisco Unified CM is integrated with the LDAP directory, Unity Connection does not automatically have access to LDAP synchronization or authentication. If you want Unity Connection users to authenticate against the LDAP directory, you must integrate Unity Connection with the LDAP directory, too. • If you import users from Cisco Unified CM, updates to Cisco Unified CM data do not automatically replicate to the Unity Connection server, so you must use the Synch Users page in Cisco Unity Connection Administration to manually synchronize Unity Connection user data with Cisco Unified CM user data from time to time. If you integrate Unity Connection with an LDAP directory, you can define a synchronization schedule that specifies when data in the Unity Connection database is automatically resynchronized with data in the LDAP directory. Note that when you add users to the LDAP directory, you still need to manually import them into Unity Connection; automatic synchronization only updates the Unity Connection database with new data for existing users, not new data for new users. • When you integrate Unity Connection with an LDAP directory, you can configure Unity Connection to authenticate passwords for web applications against the LDAP database. When you import data from Cisco Unified CM, you must maintain passwords for Unity Connection web applications in Unity Connection and for Cisco Unified CM web applications in Cisco Unified CM. Importing Users using LDAP Directory You can use Import Users functionality to import users from the LDAP directory to Unity Connection server. For more information on configuring LDAP, see the LDAP, on page 147 chapter. Creating User Accounts using BAT Cisco Unity Connection provides the Bulk Administration Tool that allows you to create, update, and delete multiple user accounts or contacts at the same time by importing information contained in a comma separated value (CSV) file. In addition, it allows you to export information about users or contacts from Cisco Unity Connection to a CSV file. For information on how to create users using BAT, see the Bulk Administration Tool, on page 248 section. Using Import Users and Synch Users Functionalities You can use the Import Users functionality to import existing Cisco Unified CM users in Unity Connection. After importing users from Cisco Unified CM, you can use the Synch Users functionality to manually refresh the information you imported from Cisco Unified CM.
