The message gets too long if you include useless information like the
schema loading and so.  Anyway, we got to the point we needed.

see slapd-sql(5)

Well, mysql is not supported, so there's no guarantee the built-in tests
work smoothly.  Anyway, on my laptop, it appears to work like a charm,
so I insist there might be something wrog with your setup.  Since the
ODBC appears to work fine, I insist with missing/incorrect data in the

That's __dynamic configuration__, it has nothing to do with run-time
loading.  Back-sql does not provide support for back-config, but it is
known to work either as a static or a run-time loadable module.

Your test is failing because a bind failed, not because the ODBC was not
configured correctly.  In fact, the test client gets an "invalid
credentials" from the LDAP operation, not from the ODBC authentication.
The bind failed because the DN the client is trying to bind as does not
exist, or cannot be found.  I don't know the reason, but I'd first look
at the data in your RDBMS, and specifically at the DN colum of
