Doesn't anybody ever read the Samba wiki ?????

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

Specifically:

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

Your smb.conf is so wrong, I find it hard to know where to start.

Lets start with, it isn't for a Unix AD domain member, the line
'security = domain' should be 'security = ads'

The 'idmap config' lines are not correct, there should be more of them.

You shouldn't use both 'winbind' and 'sssd', use one or the other. If
you decide to go with 'sssd', then you will need to ask on the
sssd-mailing, sssd is not part of Samba.

Not sure what you mean about a local user accessing the share,
local users are outside the domain and, as such, are unknown to the
domain and will be denied access.
