I did some tests using OpenBSD current and linux, both running Samba
4.17.6, and using your simplified smb.conf. Outcome is that I'm able to
reproduce (part) of your observation.
On OpenBSD current:
$ smbclient -N -U test -L 127.0.0.1
Sharename Type Comment
--------- ---- -------
IPC$ IPC IPC Service (Samba 4.17.6)
nobody Disk Home directory of nobody
SMB1 disabled -- no workgroup available
On linux:
$ smbclient -N -U test -L 127.0.0.1
Sharename Type Comment
--------- ---- -------
IPC$ IPC IPC Service (Samba 4.17.6)
SMB1 disabled -- no workgroup available
To be honest I have no clue where this is coming from, but I will keep
my eyes open. Did you share this observation on the samba mailing list?
Maybe they can be of assistance in understanding this difference in
behaviour.
