samba - Dec 2016 - Can Linux ACLs override Sticky Bits on a Samba Share?

Hi, 


I have an Ubuntu Linux server where I use Sticky Bits to help enforce specific
permissions on Samba shares:


-- Each Samba share is associated with a unique Linux group
-- Only members of the group can access the share
-- All members of the group can create new files and directories in the share
-- SGID is set on all directories. 
-- The "creator" of any new file will be the owner of the file
-- Sticky Bits are placed on all new directories via an inotify process 
-- As a result of the Sticky Bit set on directories, only the owner of a file
can move, rename, or delete a file inside a directory


This all works perfectly, as designed, including through SMB mounts on Windows
and OS X.


However, now I want to allow a limited subset of users to be able to override
the Sticky Bit rule.  I have created a second Linux group, added special members
to the group, and applied an ACL recursively throughout the share's
directory tree that gives this new group an ACL that would allow
read/write/execute on all files and directories.  However, when working through
an SMB mount, members of this second group are still unable to move, rename or
delete files that don't belong to them.   I guess this makes sense, because
really even members of the first group have read/write/execute privileges when I
look at the ACLs.


Is there a way around this problem?  Is there a way to create an ACL that will
trump (take priority over) a Sticky Bit on a directory?   Is there a specific
setting in smb.conf that would only enforce Sticky Bit rules for members of the
first group, but allow members of the second group to have the same permissions
as the owner of a file?
