You must also run the idsync resync command for the failover installation. The links between the entries are already established, and idsync resync is only needed to prime the object cache database for the Active Directory Connector. Therefore, the command is run with the -u option.
To avoid overloading Message Queue with log messages, the following must be done:
Change the Identity Synchronization for Windows log level to INFO
Run idsync resync over the entire user population in batches
You must modify the script in the previous section and run it on the failover installation Core, config-eu.gt.com. Change the parameters at the top of the script, and replace the -i NEW_LINKED_USERS option with just -u.
