4.3 Updating slapd.conf

Once the schema has been selected, the next step is to modify slapd.conf to support the selected attribute types and object classes. In order to support the inetOrgPerson object class, you must include inetorgperson.schema, core.schema, and cosine.schema in slapd.conf. The comments that begin inetorgperson.schema outline the dependency on the COSINE schema. Here are the modifications to the global section of slapd.conf:

# /usr/local/etc/openldap/slapd.conf
# Global section
## Include the minimum schema required.
include         /usr/local/etc/openldap/schema/core.schema
## Added to support the inetOrgPerson object.
include         /usr/local/etc/openldap/schema/cosine.schema
include         /usr/local/etc/openldap/schema/inetorgperson.schema
## Added logging parameters
 . . .

The database section is currently in working condition, so only a few changes are needed. To better support searches for employees, you should modify the set of indexes to include a more complete list of attributes. In addition to creating an index for the cn attribute, you'll also index the surname (sn) and email address (mail) attributes. In addition to the equality (eq) index, you'll add a substring (sub) index to support searches such as "All employees whose last names begin with C." Finally, you will add an equality index for the departmentNumber attribute so that users can search for employees within a given department. This index would not be necessary if the directory were laid out as shown in Figure 4-2 because the same effect could be achieved by beginning the search at the department ou. Here are the changes to the database section:

## Indexes to maintain
index         objectClass         eq
index         cn,sn,mail          eq,sub
index         departmentNumber    eq
 . . .

At this point, it's a good idea to verify that the location specified by the directory parameter exists and has the proper permissions. In our example, that directory is /var/ldap/plainjoe.org. If this directory does not exist, the following two commands ensure that the filesystem is ready to store data:

root# mkdir -p /var/ldap/plainjoe.org
root# chmod 700 /var/ldap/plainjoe.org
