Bite the bullet, classicupgrade to AD. 😁
You are running Samba as an NT4-style domain with ldap, so you are
possibly also using smbldap-tools, this is more than EOL, it is dead,
there is absolutely nobody maintaining it.
Samba is working hard to remove SMBv1 and a lot of what an NT4-style
domain relies on was deprecated at 4.13.0 . Windows 10 has SMBv1 turned
off by default, so you have to manually turn it back on, Microsoft could
decide to turn it off completely.
An NT4-style domain is yesterdays technology, AD is the way forward. If
you must keep your domain running whilst you test the upgrade path, then
use Samba 4 and run smbd, nmbd and winbind on the PDC etc.
