DefinitionEntryID typically an entry ID is a value that is used to uniquely identify an entry in the Directory Server Back-end. Although the entry's DN could be used for this purpose, normally the numeric entry ID is much more compact and more efficient to decode, so it is more appropriate for widespread use.


EDirectory utilizes an LocalEntryID AttributeTypes as the underlying database uniqueID value. This value is NOT replicated across servers and the value may only exist on a single server.


The entry ID is used as the key to the actual entry data in the id2entry database, and it is used in ID lists to identify entries matching the associated index key.
