Matching Rule Use definitions map certain attribute types with a matching rule definition for
extensible match filters. Extensible match filters allows clients to search using DN
components, for example, (
ou:dn:=engineering) or using an OID number, for
example, (cn:188.8.131.52:=Sam Carter). The matching rule use attribute
publishes those attribute types and matching rule combinations, which can be used in
extensible match assertions.
Typically, you define a matching rule use that is not normally specified in the attribute type definition. You can create new matching rule uses from the existing schema definitions by adding a custom schema file in the <server-root>/config/schema directory.
