AD Sync password sync issues (Event ID 611)

Event ID 611
Password synchronization failed for domain:

System.DirectoryServices.Protocols.LdapException: The operation was aborted because the client side timeout limit was exceeded.

To resolve, a registry setting has to be changed on the server running AD Sync, followed by a reboot:

  1. On the server running AD Sync, open regedit.
  2. Navigate to the key:
  3. Set the value of LdapClientIntegrity to 0.
  4. Restart the server.
  5. After the restart, trigger a new sync by manually running the task scheduler or by running the directory synchronization command DirectorySyncClientCmd.exe. A full sync is not required.
