> Force principals names to resolve to lowercase local usernames in auth-to-local rules.
This will help when the KDC is an MIT KDC or an  Active Directory and user accounts have uppercase
letters that need to be converted to lowercase letters.  For example:  {{USER1234@REALM}}
should resolve to {{user1234}}.
> *Solution*
> # Provide a kerberos-env configuration to optionally create case-insensitive rules
> # If creating case-insensitive rules, _generic_ auth-to-local rules should contain the
{{L}} option, as in:
> {code}
> RULE:[1:$1@$0](.*@REALM)s/@.*///L
> {code}
