Re: Fwd: dynlist overlay expandable attributes are not searchable

This issue has been discussed many times, and it should be clear enough
from slapo-dynlist(5) man page.  Your expectation does not comply with
the rationale of dynlist.  In fact, for your expectation to hold,
dynamic list expansion should occur __before__ filtering.  A first
adverse consequence is that indexing would be impossible.  A second
adverse consequence is that dynamic list expansion should __always__
occur for all dynamic entries that fall into the scope of any search.
This is technically possible, but it would likely be very costly.  Feel
free to submit a patch that implements such design, but I'm pretty sure
most of the dynlist users (including perhaps yourself) would then start
complaining about the poor performances of databases that use that overlay.
So, is there any other way to implement _dynamic_ posixGroup, whose
membership is determined by particular filter? Or is the whole world
using plain static groups?
