The LDIF backend to slapd(8) is a basic storage backend that stores entries in text files in LDIF format, and exploits the filesystem to create the tree structure of the database. It is intended as a cheap, low performance easy to use backend.
When using the cn=config dynamic configuration database with persistent storage, the configuration data is stored using this backend. See slapd-config(5) for more information
