I started applying an ACE to a directory that would grant a specific user read-only access to all files and folders, and I made this ACE inheritable (object_inherit,container_inherit). Unfortunately it seems that when a file is created within a directory with this ACE, the file only inherits this ACE, and not the default OWNER@, GROUP@ entries that grant the user and group their normal permissions. Previously the ACL was synthetic and we just used POSIX permissions. After applying this ACE, the ACL is real. Removing this entry still leaves a real ACL in place. How can I go back to a synthetic ACL that allows us to just use POSIX permissions to manage the files?
