/mcpThat process invisibly imported the LDAP data into a hidden Cisco Unified Communications Manager database on the Unity Connection server. When you use the Bulk Administration Tool to integrate existing Unity Connection users with LDAP users, you do the following tasks, which update each Unity Connection user account with the LDAP user ID for the corresponding LDAP user account: • Export the data from the Cisco Unified CM database into a CSV file. • Update the CSV file to remove LDAP users who don’t have Unity Connection accounts and to remove Cisco Unified CM IDs, if applicable. If any users in the LDAP directory were missing values in the field that you specified on the LDAP Setup page in the LDAP Attribute for User ID list, you must add the missing values in the LDAP directory and resynchronize the Unity Connection database with the LDAP directory. Do not enter the values in the CSV file and then import the CSV file; Unity Connection is not able to locate those users in the LDAP directory. Caution • Import the updated CSV file into the Unity Connection database. When you import LDAP user data into the Unity Connection database, existing values for the fields being imported are overwritten with values from the LDAP directory. Caution Step 1 For every Cisco Unity Connection user that you want to integrate with an LDAP user, if the value of the Unity Connection Alias field does not match the value of the LDAP user ID, use Cisco Unity Connection Administration to update the Unity Connection alias so that they do match. Step 2 Sign in to Unity Connection Administration as a user that has the System Administrator role. Step 3 Expand Tools and select Bulk Administration Tool. Step 4 Export to a CSV file the LDAP user data that is currently in the cache on the Connection server: a) Under Select Operation, select Export. b) Under Select Object Type, select Users from LDAP Directory. c) In the CSV File field, enter the name of the file in which you want to save exported data. d) Select Submit. Step 5 Download and edit the CSV file that you created in Step 4: • Remove any Unity Connection users who you do not want to synchronize with users in the LDAP directory. • For Unity Connection users who were originally created by importing data from Cisco Unified CM, enter %null% in the CcmId field. • Confirm that the LdapCcmUserId field contains the correct LDAP alias for each user. Step 6 Import the data that you edited in Step 5: • a. In Cisco Unity Connection Administration, expand Tools and select Bulk Administration Tool. b. Under Select Operation, select Update. c. Under Select Object Type, select Users with Mailbox. System Administration Guide 162 LDAP Integrating Existing Unity Connection User Accounts with LDAP User Accounts Using Bulk Administration Tool
