You appear not to understand the real concepts behind authentication and
authorization....

You can authenticate a username/password pair, regardless of location.
(standard login)

THEN you can use the username/password to retrieve and verify a
particular group for the username/password (winbind group external ACL).

THEN you can also verify a location with one of the username/password or
username/password/group tuplets.

You cannot use AD _user_ groups to assign a group membership to a
_location_ while ignoring username.

For the setup you are now describing the secure way to do it is to
ignore username completely and use the location (source IP) in an ACL.
As has been mentioned several times already.

You can _additional_ to that, to force users to login correctly (anyone
with valid username/password pair) before the external ACL gets run. But
even then the external ACL MUST ignore the login details it gets.
