Samba 4.11 disables smb1, breaking our smbfs client

Hello All,

I updated my Ubuntu system to 20.04 LTS which comes with Samba 4.13. I went to back up my system, which I do over smbfs, and it failed to mount. After some debugging I found that samba 4.11 turned off smb1.

I updated my smb.conf with the follow and it worked:

[global]
...
server min protocol = NT1

Now it works!

Cheers,
