Hello people.
I recently tried changing some settings in my samba servers that resulted in me not being able to access my library anymore from Kodi.
In particular I believe the setting in question is min protocol = SMB2.

OSX Version 10.12.4
Platform Retina MacBook Pro Late 2014
Install Method dmg
Version of Kodi 17.1 Git:20170320-fc1619b
Detailed Instructions to Reproduce the Problem (The more specific the better.)
What I did was simply force the minimum protocol on the server to be SMB2, shares worked before the change and work again after this setting is commented out.

Below an excerpt of the debug log when trying to access a share with the option min protocol = SMB2

Code:

But this isn't reproduced on a server without this option enabled, below an example.

I'm not sure this is intended behaviour. Could you please guide me to troubleshoot this?

I think libsmbclient might simply not support smbv2

[wabbajack]

I think libsmbclient might simply not support smbv2

So does this make it an MacOS specific issue or is it the library that Kodi uses on all platform and therefore something that is currently working as intended?

[Rechi]

We are currently not able to build samba 4.1 or newer, which was the first version supporting SMB2/3 protocol for libsmbclient.

Edit:
This issue doesn't occur on Windows, because there libsmbclient isn't used and if you use Linux your distribution has most likely packaged a newer version, which supports SMB2/3.

[wabbajack]

I see. I believe this might be something quite relevant though, it might become a security issue.
Would this be appropriate for a feature request?

Is this problem still open ??
I use Kodi 17.4 on MacOS Sierra and can not connect properly to OpenElec 8.1.1....
Even when I force OpenElec to use SMB1, the connection while playing files from there is not reliable.

Thanks for your information.

Same with all version of LibreELEC.
Upgraded to HiSierra and can no longer access SAMBA file shares on the iMac from LibreELEC Kodi Krypton no matter which SMB protocol I select.

Seems Apple have thrown another spanner in the works.
They also removed Telnet, and FTP servers with the Hi Sierra update. NOT Happy !

Only suggestion is to use NFS Manager and use NFS file sharing on a Mac.

EDIT or try turning off Packet Signing in macOS:

I am now able to Add Video shares again simply by using Zeroconf in Kodi.
