from what I understand this should only work if the attack is carried out via intranet, not via internet.
Right?

Yes the domain controller LDAP service binds to a LAN IP.

Samba has released the fix yesterday:

The testing package is on production in my DC since yesterday: Iā€™m going to release it today! Please provide some testing feedback!

Tested on a fresh VM and on my home server:

On the fresh VM it just worked. I tested joining and domain logon from Windows 7.

On the home server I had to reset permissions to make ACL shares work again but this is not related to nethserver-dc I think. Domain logons from Windows 10 worked normally after update.
