Hi !

We are trying to define (in our own ldap schema) an IA5String attribute type that is required to be managed (from our ldap clients) as "case insensitive"

"greaterOrEqual" and "lessOrEqual" filters are required to be managed over this attribute, so we wanted to assigne (in its attribute type definition) an ORDERING matching requesting "case insensitive" behaviour

According to RFC4517 (http://tools.ietf.org/html/rfc4517) there is NO any ordering Matching Rule for IA5String syntax AND case insensitive support. We tried with the "caseIgnoreOrderingMatch" .. but slapd returns and error (at schema loading) as attribute type syntax (IA5String) is not allowed for this "ordering match rule"

We checked that defining the attribute as "PrintableString" works (as "caseIgnoreOrderingMatch" is a valid matching rule for that sysntax according to RFC4517) ... but we are really interested in IA5String syntax ....

Does openLDAP server technolgy provide a "case insensitive ordering match" method for IA5String syntax ?

Thanks in advance

BR / Antonio
