wbinfo -u & -g just shows that the users and groups exist in AD.
getent will only show windows users & groups if everything is set up

I wouldn't worry about the above.

Now this doesn't really make sense, unless it is pulling in some
package(s) that weren't installed before.

How 'idmap config' is setup changed at 4.6.0, but you seem to be
saying you are still using 4.5.16 on Debian 9, so this shouldn't come
into play.

You should be able to use 4.8.2 from Louis's repo on Debian 9, I would
usually advise using the latest stable version of Samba possible
(though there have been exceptions).

Can you please post your smb.conf again, I cannot remember what it
