+underlined text+1. Rename Legacy*Keys#KEYS to match the pattern LegacyNtmlPropKeys#NTLM_AUTH_KEYS. We have several instances where we just use the KEYS var and many more instances where we call it XYZ_KEYS
 
2. Rename LegacyLDAPPropsKeys#NONPOSTFIXED_LDAP_KEYS and #POSTFIXED_LDAP_KEYS to LDAP_KEYS_*  to add the description as a suffix.
