Make ACL matching case insensitive for users/groups.
Ranger imports LDAP users/groups while preserving case by default, but Active Directory environments with uppercase users/groups often import to lowercase at the OS level (eg.Centrify), causing unintuitive ACL mismatches as Ranger is doing case sensitive ACL matching. I've seen this issue at a couple of large financials now and while it's easily to workaround by configuring lowercasing on user/group imports it could be handled better automatically similar to the way Ambari changed to make user/group handling case insensitive (
AMBARI-17383), rather than having to fix it on an environment by environment basis.
This could have a config setting to disable case insensitive ACL matches to maintain backwards compatibility if needed.
