My system info :
Linux berry 4.4.34+ #930 Wed Nov 23 15:12:30 GMT 2016 armv6l GNU/Linux 
(raspberry pi 3 with latest raspbian)
openldap 2.4.44 built from sources : "./configure --prefix=/opt/openldap-2.4.44
--enable-sql"
Mysql deployed from repository : 5.5.54-0+deb8u1 (Raspbian)

followed the mysql specific README from the rdbms sources folder (created the
db, schema & test data)

Now, when I try to start-up the server I get :

My related DB content :
mysql> select * from ldap_oc_mappings;
+----+---------------+------------+--------+-------------+-------------+---------------+

4 rows in set (0.00 sec)

Now, as far as I can tell what is happening is that when loading the schema the
first one (inetOrgPerson) is being overwritten by the second (document) without
a terminator, ending up with an "documenterson" which obviously doesn't exist.
