Hi, A Win Sync between FDS and Active Directory failed on our servers due to FDS reboot. Errog log says : (delta:636) - Can't locate CSN 48f3e8cc000100020000 in the changelog (DB rc=-30990). The consumer may need to be reinitialized. Does it mean that a consumer reinitialization may be done ? In this case, does it erase any data in AD ? What happens with AD-only attributs ? IS there any method to resync without deleting AD data ?
