Overview of Standard Indexes

Because of the need to maintain default indexes and other internal indexing
mechanisms, the Directory Server also maintains certain standard index files.
The following standard indexes exist by default, and you do not need to
generate them:
•
id2entry.db4
database files can be recreated from this one.
•
id2children.db4
searches that examine an entry's immediate children.
•
dn.db4
examine an entry and all the entries in the subtree beneath it.
•
dn2id.db4
distinguished name to its ID number.
