If there is no 'client min protocol' and/or 'server min protocol' set
in smb.conf, then you will be using the default setting. Before Samba
4.11.0 , the default was 'CORE', from 4.11.0 this was raised to
'SMB2_02'.

'min protocol' is a synonym for 'server min protocol'

You shouldn't have to set any 'min protocol', negotiation should find
the best one to use, it should start at SMBv3 and work down from that.

We are going to need wireshark traces from both the Windows connecting
and the other (MacOS ?) machine that connects.
