He's talking about "Administrators" the SID (group).

In any case, I'd start with a throwaway share (or save the permissions
with subinacl if I had to use a live one).  Then remove the inherited /
default DACL from a subdirectory:

mkdir sub
setfacl -k sub
setfacl -b sub

Then check how this behaves w.r.t. POSIX permissions and file ownership.
Populate this directory with files and check those, too.  The ~/.ssh
directory and their content shouldn't have any DACL on them in any case
if you c want to be sure it works the way sshd is wanting it to.


Regards,
Achim.
