I have configured vfs_streams_depot to support some NTFS metadata. The
metadata files are being created but permissions are not inherited from
their parent objects. Only a user who created the metadata has full access
to it.

For example, we have one file object "file1" and few users having full
access to it. If one user creates metadata information all other users
cannot read nor write metadata.

Tried to configure ACL (everybody read-write access) on the
<streams_depot:directory> but the actual permissions are still not

The type of metadata being used is MAC tags.

Running samba-4.2.10-7.el7_2.x86_64 on CentOS 7.2.1511.
Stock kernel 3.10.0-327.28.2.el7.x86_64

Samba is running as AD member. The shares are on ext4 file system.
