A matching rule use lists the attribute types that are suitable for use with an extensibleMatch search filter.

  • Use ldapsearch to view the Directory Server’s published list of matching rule uses using the multi-valued operational attribute, matchingRuleUse, which publishes the definitions on the Directory Server if any. The attribute is stored in the subschema subentry.
