[Samba] Cannot set ACL rights for group "Authenticated Users" (SID S-1-5-11)\

Very embarassing indeed :-()

What I do: Put the "Authenticated Users" to the list of users already
having access. I then assign some rights (let's say Read and Write) and
then I press OK.
What I see: After reopening the GUI (or pressing Update), the entry has
simply vanished. Checking with getfacl shows, that "Authenticated Users"
have received no ACL entry.

What is even stranger: I set the permissions for "Authenticated Users"
with setfacl and edit a completely different domain user ACL entry and
press OK again.
What I see: The ACL entry for "Authenticated Users" has gone. The ACL
entry for the domain user is perfectly oK. Again, I checked with getfacl
that what the GUI shows indeed is correct.

I'm using security=ADS - may this have an impact?
