The FIM/ILM AD Management agent allows the nomination of a list of specified DCs in connection priority order, to override the default arbitary selection of any DC on a domain. When the AD Sync Changes plugin is used in a multi DC environment where there are even minor replication delays, the plug-in can fire before the DC to which the AD MA performs the delta import (change log read) has been updated, causing the change to be missed (in particular object deletions it seems). The above scenario could be mitigated if the plugin configuration was allowed to mimic this exact capability, thereby reducing (if not elminating) the possibility that changes are missed.
