Any changes in Windows should be be shown by getfacl, but the directory
ownership shouldn't change and the user making the alterations must
have the required privileges to make the changes.

What is in the 'samba_usermap' ?

As you are trying to use Windows ACLs, you should follow the info on
the page you linked and stop getting creative ;-)
Remove the 'guest ok' line, it is the default.
Remove the two 'mask' lines, the last line is actually telling Samba
to ignore them.

Yes, whilst every user must have a unique uidNumber and every group
must have a unique gidNumber, there is nothing stopping a user and a
group having the same number.
