# caseIgnoreMatch

Compares an assertion of Directory String syntax to a value whose syntax is the ASN.1 DirectoryString type, or one of the alternative types.

The rule evaluates to TRUE if and only if the prepared attribute value string and prepared assertion value string have the same number of characters, and corresponding characters have the same code point. For the comparison, characters are case folded, and only insignificant white space handling is applied.
