> 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}
