An EQUALITY Matching Rule that rule compares an assertion value of the Directory String syntax to an attribute value of a syntax (e.g., the Directory String, Printable String, Country String, or Telephone Number LDAP Syntax) whose corresponding ASN.1 type is Directory String or one of its alternative string types.

The CaseExactOrderingMatch rule evaluates to TRUE if and only if, in the code point collation order, the prepared attribute value character string appears earlier than the prepared assertion value character string; i.e., the attribute value is "less than" the assertion value.

In preparing the attribute value and assertion value for comparison, characters are not case folded in the Map preparation step, and only Insignificant Space Handling is applied in the Insignificant Character Handling step.

The LDAP definition for the CaseExactOrderingMatch Matching Rule is:
