To trigger a full password sync, perform the following steps:
1. Open PowerShell, and then type Import-Module DirSync
2. Type Set-FullPasswordSync, and then press Enter
3. Type Restart-Service FIMSynchronizationService -Force , and then press Enter
Once this is complete, you should see a series of EventId=656 (Password Sync Requests) and EventId=657 (Password Sync Results) indicating that your full password sync has kicked off.
