!!! Overview
[{$pagename}] 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]
[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.

![OpenDS]
The entry ID is used as the key to the actual entry data in the [id2entry database|Definition -- id2entry Database], and it is used in [ID lists|Definition -- ID List] to identify entries matching the associated [index|Definition -- Index] key.
