Subject: [PATCH] Update the schema backend so that the creatorsName, createTimestamp, modifiersName, and modifyTimestamp attributes are included in the subschema subentry as recommended in RFC 4512 section 4.2. The create timestamp will be set to the oldest modification time of all the schema configuration files. The modify timestamp will be initially set to the youngest modification time of all the schema configuration files, but if the schema is updated with the server online then the modifiersName and modifyTimestamp will be updated accordingly.
