The OpenLDAP directory that we have setup is a pretty basic one. We are using objectClasses organizationalPerson and inetOrgPerson. Here is a sample of an export to LDIF from the application GQ:
dn: cn=John Doe,dc=brosco,dc=com
objectClass: top
objectClass: organizationalPerson
objectClass: inetOrgPerson
cn: John Doe
sn: Doe
givenName: John
uid: jad
telephoneNumber: 1111
