конфигурация backend для slapd (configuration backend to slapd)
DATABASE OPTIONS
Database options are set in entries named
olcDatabase={x}<databasetype>,cn=config and must have the
olcDatabaseConfig objectClass. Normally the config engine
generates the "{x}" index in the RDN automatically, so it can be
omitted when initially loading these entries.
The special frontend database is always numbered "{-1}" and the
config database is always numbered "{0}".
