Samba password problem

Hi,

I have a new Apple Macintosh laptop and I am trying to use Samba to send files back and forth from my Ubuntu Mate laptop and vice versa. I am not familiar with Samba or with modern Macs. I am pretty familiar with Linux. There are no Windows machines in my network.

My user name is Bob on the Mac and bob on Ubuntu Mate. The passwords for logging on as the user are the same on both machines.

I have turned on File sharing on the Mac and set the weird option to make the password for Bob to be usable by Windows.

On the Mac I went to

System Preferences->Network->WiFi->Advanced...->WINS->Workgroup

and changed the Workgroup to HOME (having first changed the WINS server to the IP address of the Ubuntu Mate).

On Ubuntu Mate I changed workgroup to HOME in /etc/samba/smb.conf.

On the Mac, in Finder I can go to the network and I can see the Ubuntu Mate machine and can connect as Guest. (I can't see any folders, possibly because I haven't explicitly set any up to be shared for guests.)

On the Mac, if I try to connect as Registered User, it supplies the user name "bob" and asks for the password. I type the password and click Connect. The dialogue box shivers and asks me again, obviously not accepting the password and/or user.

On the Ubuntu Mate, in caja, I can use the Browse Network bookmark and the name of the Mac appears. If I double-click on the Mac's icon, I get a dialogue box that fills in Username as bob; Domain as HOME and asks for Password. The dialogue box vanishes and reappears, obviously not accepting the password and/or user. If I change the Username to Bob (with capital B) the same happens. There does not seem to be a way of connecting to the Mac as guest.

Any ideas how I can connect as Registered User in either direction?
