How can we ever get rid of this "huge directory" problem? AFAIK the most time
consuming operation is the PROPFIND on huge collections, isn't it? So if we
could map this propfind to a DASL-request this could be much faster if an
appropriate index exists. What do you think?
This is no objection agains your proposal, I'm just thinking of a cleaner
solution as we are getting this problem over and over again under different
circumstances.
Cheers,
Daniel
