What Does Already Work?

I single domain single DC

I multiple DCs with some hacks(FS replication)

I joining workstations, automaticdns updates

I management withWindows-tools(mmc, active directory users andcomputers, ...)

I group policies (management viammc)

I schema extensions: e.g.Zarafa-integration(open source group ware)
