Ruslan Dautkhanov commented on HIVE-13590:
------------------------------------------
Sorry, I am not following. auth_to_local is already being applied to Kerberos
principals. Why applying auth_to_local to LDAP principals is different than
mapping Kerberos principals? Why it introduces security risk? Please elaborate.
Thank you.
