Still not really right ;-)

encrypt passwords = yes # you do not need this, it is a default setting
auth methods = winbind # remove this, it is not required

winbind trusted domains only = no # you do not need this,
                                    it is a default setting

passdb backend = tdbsam # you do not need this, it is a default setting
obey pam restrictions = yes # remove this, it is not required

Words fail me on the above, default lines, duplicate lines, acl_xattr
is a share and in global, the other two 'vfs objects' don't have any of
the other required lines to make them actually work.
Can I suggest you use Windows ACLs (the info howto is on the SAmba
wiki) and remove all that clutter.

Yes, but have you given Domain Users a gidNumber ???

If you haven't given Domain Users a gidNumber and are using Samba
4.6.x, you can follow the info here:

https://wiki.samba.org/index.php/Idmap_config_ad

Probably because you haven't given Domain Users a gidNumber, have you
spotted the running theme here yet ?

Unless we are told what any possible problems on the wiki are, we
cannot fix them, or you could register and fix them yourself ;-)
