3.1.1.4.5.37 msDS-LocalEffectiveDeletionTime
The msDS-LocalEffectiveDeletionTime attribute exists on AD DS and AD LDS on Windows Server 2008 R2 operating system and later.
This attribute contains the value that a replica maintains as the time when the object was transformed into a tombstone or deleted-object.
Each DC is permitted to modify this value locally for implementation-specific reasons outside the state model. Therefore, this value does not necessarily accurately reflect when the object was actually transformed. However, no replica is permitted to modify this value to be earlier than the actual time that the object was transformed. This value is not replicated. Therefore, for a specific object, each DC can have a different value for this attribute.
When the Recycle Bin optional feature is enabled, each replica will transform the deleted-object into a recycled-object some time after the difference that exists between the current time and the value of msDS-LocalEffectiveDeletionTime is greater than the value of the deleted-object lifetime.
When the Recycle Bin optional feature is not enabled, the DC makes no use of this value. When this attribute exists on a tombstone, it is not used by the replica.
