Is the Mozilla LDIF export bogus?

[Jonathan Coles <jcoles0727@rogers.com>]

I wanted to set up a simple LDAP server and thought that the Mozilla's 
LDAP capabilities would be a good place to begin. However, I notice that 
their LDIF entries lack any "dc" attribute. For example,

dn: cn=A User,mail=auser@hotmail.com
objectclass: top
objectclass: person
objectclass: organizationalPerson
objectclass: inetOrgPerson
givenName: A
sn: User
cn: A User
mail: auser@hotmail.com
o: ThisOrg

(I have changed the names for privacy)

What would I use as a suffix in the slapd.conf file? Is this LDIF 
actually usable to create an LDAP database?
