Equality Matching: objectIdentifierFirstComponentMatch

Description:

Servers which allow subschema entries to be modified by clients MUST support the following matching rules, as they are the equality matching rules for several of the subschema attributes.

Implementors should note that the assertion syntax of these matching rules, an INTEGER or OID, is different from the value syntax of attributes for which this is the equality matching rule.

If the client supplies an extensible filter using an objectIdentifierFirstComponentMatch whose matchValue is in the "descr" form, and the OID is not recognized by the server, then the filter is Undefined.
