source code it appears that it is not supported. However, integerMatch is
actually caseIgnoreIA5Match, so one would think that using
caseIgnoreIA5OrderingMatch would be the same thing.

Despite the Admin guide for version 2.0 and 2.1 which has
caseIgnoreIA5OrderingMatch as a common matching rule, I get the following
when attempting to use it:MatchingRule not found: "caseIgnoreIA5OrderingMatch"
