RE: Case Ignore Ordering matching rule for IA5 String sysntax ?
OK ... we will check that approach.
Do you know if it was something forgotten in the RFC4517 ?... it
really odd (to me) that PrintableString (that is a subset of IA5String)
and DirectoryString (that is a superset) are allowed syntaxis for
"caseIgnoreOrderingMatch" ... but IA5String is not allowed to use it
(maybe I am missunderstanding/mixing things ....???)
Thanks a lot

No. It doesn't because there's no standard track definition for it.
However, there's nothing preventing OpenLDAP software from supporting
this non-standard track feature. Adding custom matching rules is
