In your ldap_oc_mappings there's no way
to find how to map the entry you provided
to an objectClass that is known to your
back-sql instance.

this has REALLY nothing to do with back-sql:
the entry you're using can be totally fine,
compliant with the latest (or backward
compatible with the earliest) LDAP standard,
but if the back-sql doesn't know how to store
it in the RDBMS there's no way it can work.
back-bdb stores the entries internally, so
as soon as they're fine the always get stored.
I assume, from wehat you're stating, that you
never had a look at slapd-sql(5), which clearly
statesm, in its opening:
The primary purpose of this slapd(8) backend is to PRESENT
information stored in some RDBMS as an LDAP subtree with-
out any programming (some SQL and maybe stored procedures
can't be considered programming, anyway ;).
...
It is NOT designed as a general-purpose backend that uses
RDBMS instead of BerkeleyDB (as the standard BDB backend
does), though it can be used as such with several limita-
tions. You can take a look at http://www.openl-
dap.org/faq/index.cgi?file=378 (OpenLDAP FAQ-O-Matic/Gen-
eral LDAP FAQ/Directories vs. conventional databases) to
find out more on this point.

Apparently, you didn't load the meta-data.
"backsql_create.sql" populates an example RDBMS
__BEFORE__ it is back-sql enabled. You need
to populate the back-sql aware portion of the
database with "testdb_metadata.sql" before you
even run slapd with any instance of back-sql.
This is clearly described in slapd-sql(5) under
the "METAINFORMATION USED", although, I admit,
the "testdb_metadata.sql" is never explicitly
mentioned (sig!). In any case, crafting meta-
data for back-sql is not a simple exercise, so
I wouldn't suggest to start playing with slapd
by using back-sql, and significantly by trying
to load the database from scratch using add
operations!
It is very unlikely you can write your meta-data
in order to entirely load a database, even for
a very simple example. Writing thru back-sql
should be an exception; routine writes should
occur directly in the RDBMS.
I hope I was clear enough.
