Not quite, the last versions of Samba .3 supported SMBv2 but Samba
3.x.x is EOL and has been for a number of years.

What do you mean by 'the old nmbd daemon' ?
samba 4 still has the nmbd daemon and is capable of running just like

No, you must use the nmbd that comes with Samba 4, the problem is that
you will have to use SMBv1 at both ends. This is not really a problem,
it is just a bit insecure and you might not need to run nmbd. It might
help if you can describe your setup in more detail and if you have
anything that must use SMBv1 (something that will not work without SMBv1).
