Overview #

This is an Extensible Match matching rule with an OID of 1.2.840.113556.1.4.804. A match is found if any bits from the attribute match the value. This rule is equivalent to a bitwise OR operator and if often referred to as the LDAP_MATCHING_RULE_BIT_OR.[1]

We show examples of this Extensible Match usage under Filtering for Bit Fields

Not all LDAP server vendors provide complete matching rules. The OID's shown here are Microsoft Active Directory specific and will probably not work on other server implementations. We wish some of the other LDAP server vendors would add support for these Extensible Match Rules.
