[Samba] Strange Inheritance of folder rights in Version 3.026a

[Jens Nissen]

Assume folder hierarchy /service/f1/f2/f3.
I have initially disabled acl inheritance in smb.conf for "service".
Neither folder service,f1,f2,f3 has the right "Inherit rights from
parent" set.
(I had to translate the Windows-check-boxes' texts, I hope that it is
possible to follow my actions)

(A) Now I apply the property "Inherit rights from parent" to folder f2.
Once I press OK, the right disappears again.
>> Obviously, the right was set, then the right to inherit the right was
inherited from folder f1 and thus finally deleted again from folder f2.

(B) Now I fool Samba by setting the advanced rights
"Inherit rights from parent" and "Propagate rights to contained folders"
to folder f2.
This sets the right "Inherit rights from parent" to folder **f3** (only).
>> Again, it looks as though the right is first set on f2, then
propagated to f3, afterwards inherited from f1 and thus finally deleted
from f2.

All this is very different from Windows and User expectation.
IMHO, the right to inherit a right from the parent should not be
inherited from the parent itself!

Could you fix this, please?

Kind regards,

Jens
