Pierre Sauvage updated HADOOP-13984:
Description:
It is possible, with /L, to force lowercase in auth_to_local mapping process
(e.g. LOWER@HADOOP.DOMAIN -> lower).
But the opposite, using /U, is not possible
(e.g upper@HADOOP.DOMAIN -> UPPER)
The ability of forcing uppercase is important when using Active Directory with
cross-realm trust since Active Directory is case insensitive (you can both
kinit foo...@ad.domain.com and foo...@ad.domain.com).
