Actually, looking at it again, I'd do it a bit differently now. It should 
probably be a global overlay instead of a per-database overlay, so that it can 
publish a highestCommittedUSN in the rootDSE. It also should not maintain its 
own counters, it should just map CSNs to USNs (which are 64 bit unsigned 
integers).

By the way, yet another bug in ActiveDirectory, both the Interval syntax and 
the LargeInteger syntax have the same OID, even though they're distinct 
syntaxes. Idiots...
