252 Chapter 19. Lightweight Directory Access Protocol (LDAP)

suffix "dc=acmeuniversity, dc=edu"

The rootdn entry is the DN for a user who is unrestricted by the access control or administrative limit

parameters set for operations on the LDAP directory. The rootdn user can be thought of as the root

user for the LDAP directory. The rootdn line needs to be changed from:

rootdn "cn=root, dc=your-domain, dc=com"

to something like:

rootdn "cn=root, dc=redhat, dc=com"

rootdn "cn=ldapmanager, dc=my_organization, dc=org"

Change the rootpw line from:

rootpw secret

to something like

rootpw {crypt}s4L9sOIJo4kBM

In the above example, you are using an encrypted root password, which is a much better idea than

leaving a plain text root password in the slapd.conf ﬁle. To make this crypt string, you can use Perl:

perl -e "print crypt(’passwd’,’a_salt_string’);"

In the previous Perl line, salt_string is a two character salt, and passwd is the plain text version

of the password.

You could also copy a passwd entry out of /etc/passwd, but this will not work if the passwd entry

is an MD5 password (the default in Red Hat Linux 7.3).

19.6.2. The schema Directory

New to OpenLDAP version 2, the schema directory holds the various LDAP deﬁnitions, previously

located in the slapd.at.conf and slapd.oc.conf ﬁles. All attribute syntax deﬁnitions and object-

class deﬁnitions are now located in the different schema ﬁles. The various schema ﬁles are referenced

in /etc/openldap/slapd.conf using include lines, as shown in this example:

include /etc/openldap/schema/core.schema

include /etc/openldap/schema/cosine.schema

include /etc/openldap/schema/inetorgperson.schema

include /etc/openldap/schema/nis.schema

include /etc/openldap/schema/rfc822-MailMember.schema

include /etc/openldap/schema/autofs.schema

include /etc/openldap/schema/kerberosobject.schema
