this should be no big problem.

i think a pool of static and common used indexes (e.g. uid, cn, 
sambaAccountName ...etc) should be always set.
as olc-configuration can be setup now automatic via backend-provision 
(the "normal" olcIndexes are taken form slapd.conf
during conversion), every wanted/additional index can be generated/added 
on the fly at any time, as long as olc is used.
