With a regular filesystem, if I create a directory '/data/dir1/dir2/', a user without the 'execute' permission on '/data/dir1' is denied access to '/data/dir1/dir2/' even if he's granted access to '/data/dir1/dir2/' itself, i.e. he has not the right to traverse the tree.
But not with Ranger. If my filesystem permissions are set to '000' for all the directories and I have a policy granting access to '/data/dir1/dir2/' to my user, this user should not be able to see '/data/dir1/dir2/' since he has no access to '/data/dir1/'. But he can!
1. Is this the expected behavior?
2. If so, what is the meaning of the 'execute' permission in Ranger?
3. How to get my expected behavior?
directories have their permissions set to '000' in my filesystem, so
Ranger, no user has access to any of them. Then I create a
policy in Ranger for '/dir1/dir2/' with 'rwx' permissions for user A.
User A has now access to this directory, contrary to what I was
expecting. Because since there is no policy with the 'execute'
permission for '/dir1/', I
was expecting that user A couldn't access '/dir1/dir2' (because on a
regular filesystem, one need to traverse all the hierarchy of
directories and so to have the 'execute' permission on all the parents).
