Chapter 5. Database Creation and Maintenance
This section tells you how to create a slapd database from scratch. There are 
two ways to create a database. First, you can create the database on-line using
 LDAP. With this method, you simply start up slapd and add entries using the 
LDAP client of your choice. This method is fine for relatively small databases
(a few hundred or thousand entries, depending on your requirements). This method works 
for database types which support updates.
The second method of database creation is to do it off-line using special utilities 
provided with slapd. This method is best if you have many thousands of entries to create, 
which would take an unacceptably long time using the LDAP method, or if you want to 
ensure the database is not accessed while it is being created. Note that not all database 
types support these utilitites.
