stopping and restarting the service, as was required in earlier versions. You
need two files for this configuration: a back end that has only a minimal
configuration and a front end that uses a traditional format that is compatible
with and accessed by external programs, using established standards.

Creating Your Schema

Start creating your schema by loading some premade schema files. This
makes configuration faster and easier by preloading some settings. If you are
building an enterprise server, read the official OpenLDAP documentation and
start from scratch so that you know precisely what everything on your server
is doing and why. For the example in this chapter, load these three files into
the directory using the following commands:

matthew@seymour:~$ sudo ldapadd -Y EXTERNAL -H ldapi:/// -f
/etc/ldap/schema/
cosine.ldif
matthew@seymour:~$ sudo ldapadd -Y EXTERNAL -H ldapi:/// -f
/etc/ldap/schema/
nis.ldif
matthew@seymour:~$ sudo ldapadd -Y EXTERNAL -H ldapi:/// -f
/etc/ldap/schema/
inetorgperson.ldif

Next, create a file called backend.matthewhelmke.com.ldif with
these contents:
