I have tried adding ntlm auth = yes to the extra options settings, and local master browser is definitely disabled. Same bloody error.
I'm wondering if I'm using the wrong authentication credentials. On my server, I have the root user, and a single non-root user called john. When I try to access my SMB shares, what username/password should I provide? Is it just the user john and the password for that account? Or does smbd want a different password?
My only real clue is the SPNEGO login failed: NT_STATUS_NO_SUCH_USER error.
I have attached my smb.conf, and my smbd and nmbd statuses.
