When Normalizing a legacy configuration with the Profile Creation Utility, the tool can be instructed how to normalize exceptional Camel Case keys by making use of the strings listed in the following file.

conf/UpperCaseWords.txt

By default, this file contains the following lines.

DN
DNS
MSCA
AWS

Therefore, when normalizing to kebab-case, the utility formats subjectDNCache as subject-dn-cache instead of subject-d-n-cache. Edit this file to add additional exceptions.
