This certainly is a big challenge, but nothing is impossible in
software.  You would either have to be key-value based (in which case we
need a new abstraction in ldb_tdb, such as is planned for a future
ldb_ntdb and any future ldb_mdb), or implement LDAP semantics, including
the very fiddly details of the schema handling.  Much of this is
currently pushed in to ldb_tdb via our schema pointers. 

However you decided to do this, the trick would be to add a new mode to
source4/dsdb/samdb/ldb_modules/samba_dsdb.c, just like the openldap

Have a look at:

and then see how that sets things up.
