I recall we had a few ideas last year, but they came up a bit late.
Anyone still have some wish list items for this year?
What about the todo list? Anything good in there?
There are also occasional requests for additional matching rules
support,  that may be something to add.
The Forth based engine also sounds promising.
Maybe an overlay to implement USN,  like the uSNChanged attribute in
Active Directory<http://support.microsoft.com/kb/891995>   I'd imagine
USN support is required for Samba4 to use OpenLDAP as a backend,  and it
would just be handy since some tools/scripts assume AD-isms.

Just a thought.

You mean like the USN code currently in head? ;) IIRC, it still needs a little bit of work to polish it off.


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...
