samba - Jan 2019 - How to identify the operating system of a client?

My goal is to distinguish between Mac and Windows clients on a Samba 
server in order to provide shares with vfs_fruit only to Mac clients.

So I assumed using the variable substitution %a which contains the 
architecture of the remote machine would be the correct way forward.
But as it turns out, a Windows 10 client is reported as having the 
architecture "OSX".

Short of agressively scanning a remote client with nmap, does anyone 
have a suggestion on how to solve this problem?

Thanks!

- Stephan

I'm using Samba 4.5.12-Debian

Let me rephrase the question in hope for an answer:

Is it at all feasible to identify the operating system of a client?

Thanks,
Stephan

no, not really. We try to match by the list of supported SMB dialects in the 
SMB1 negprot, but that is really just guesswork.
