> *Use Case:*
> If user's LDAP / AD  has uppercase usernames and produce uppercase user 
> Kerberos principals. When doing the initial user sync into Ranger, the 
> default setting of "lower" causes all their user names to be saved in lower 
> case, meaning they don't match the Kerberos principals that LDAP / AD is 
> handing out. 
> It seems to me the more sensible default for both username and group case 
> conversion should be "none" and to just use whatever the backend directory 
> hands out, as-is, to prevent unexpected confusion such as this.
> *Proposed Solution:*
> Change Ranger's default settings for below given properties : 
> ldapGroupSync.username.caseConversion  = "none" 
> ldapGroupSync.groupname.caseConversion = "none"
