RE: LDAP schema propagation to the backend
I think the penalty in performance is so big we should consider defining a
core syntax and matching rule set (a set that all backends support) and then
defining extensions to this set per backend.
This way we could optimize queries because the backend has knowledge of the
core set. This is actually done in other LDAP servers (Netscape per
example... which defines a core set and then can be extended via a plugin).
what do you think?

But watch out... CIS may not behave exactly like caseIgnoreMatch.
caseIgnoreMatch does more than just case ignoring (it also ignores
"extra" spaces). To be able to use the SQL matching, it must
be more relaxed than the LDAP matching rule.
