This is needed because the schema can be extended with objects whose prefixes not present in the prefixMap, which at this point this causes the samba4 to crash after startup.

why don't you use the dsdb_schema->prefixes array, there it's already
kept in memory, and new attributes or objectclasses are added once every
   few month...we should avoid keeping it in memory twice.

do you know the algorithm, that's used by windows servers to create a
new oid mapping? we need to match that algorithm.
