3.1.1.3.4.4 LDAP Matching Rules (extensibleMatch)

The following sections describe the matching rules supported by DCs when performing LDAP search requests. Unlike, for example, extended controls and extended operations, there is no attribute exposed by the DC that specifies which matching rules it supports. The identifiers for these matching rules are used in an extensibleMatch clause in the filter portion of a SearchRequest, as described in [RFC2251] section 4.5.1. Matching rules are identified by an OID that corresponds to a human-readable name, as shown in the following table.
