Hello Stefan,
had the same problem here, as you said adding "ntlm auth = yes" solved it, so yes it will work with this added to the global conf. 
The problem comes from this option being set to "no" by default with the new versions.
Don't know about setting this specific parameter for a share only, interested in the answer.

At a customer they still have some old VMs around that run Windows XP.

Yes, I already provided them with newer VMs ... but the users still
need/want the old machines as well.

Now the batch file with the "net use" statements fail, as far as I have
researched because of the weak and outdated NTLMv1:

[2017/07/27 11:11:08.538343,  2]
  ntlm_password_check: NTLMv1 passwords NOT PERMITTED for user vmuser1

I assume I can enable that via the parameter "ntlm auth = yes"?
Currently it is "no", sure.

It's a global parameter, according to the man page, is there a way to
only enable NTLMv1 for this specific share?

thanks, regards, Stefan
