Core schema are defined by RFCs. If the RFC defines no matching rule, then there isn't one in the schema. If you want to see this changed, I advise filing an RFC to update the schema definition. For this particular attribute, see <https://www.ietf.org/rfc/rfc1274.txt> You can, of course, force matching rules for your search. See the slapcat manpage for examples of how to force matching rules. --Quanah -- Quanah Gibson-Mount Sr. Member of Technical Staff Zimbra, Inc A Division of VMware, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration
