samba - Dec 2022 - Samba support for Sonos S1 versions 4.15 and above

Hello?everyone,

Since Samba version 4.15 I have not been able to connect Sonos S1 to 
Samba. I have tried this on Ubuntu 22.04. There are some permission 
changes on Ubuntu. So I also tried Debian unstable (sid) which has Samba 
version 4.17, but there I have the same result, Sonos says permission 
denied. It works fine on Samba version 4.13 in Debian 11 and Ubuntu 
20.04.

As a work-around I modified a node-based SMB server details at 
https://barrydegraaff.nl/sonossmb/ that works well and gives me some 
idea of how Sonos S1 has implemented SMB protocol. So at least I have my 
music for Christmas.

With the smb.conf as below I am able to browse the defined share with 
SMB1 and ntlmv1 authentication using Samba version 4.17, but then Sonos 
does not work. If I do the same on 4.13 it works. When I use smbclient 
on my self baked node-smb server it works as well, the spnego=no and 
ntlmv2=no on the client are required to make smbclient work. Sonos does 
not seem to use lanman authentication as that is not implemented in the 
node-smb server.

I have seen this wiki 
https://wiki.samba.org/index.php/Samba_Features_added/changed#NTLMv1_authentication_disabled_by_default
but that does not help me.

Other then Wireshark and dumping the Sonos firmware can you give me any 
tips on how to resolve this issue?

Thanks?and?merry?x-mas.

Barry

I use SONOS against my Ubuntu-based fileserver.

The only two [global] settings I need are:

         ntlm auth = yes
         server min protocol = NT1
