So if the user hasn’t provided the domain part it will add the domain/workgroup part automatically. But now in my testing it seems that it doesn’t actually affect this. Setting it to ’no’ doesn’t block authenticating with only the username part and I can see in the log that “\user” is still mapped to “DOMAIN\user”.

That this parameter doesn’t appear to work the way I thought it would, meaning it affecting the mapping of the username to domain user.

OK, it doesn't matter how I try to connect or log in, I can use 
'username' or 'DOMAIN\username' and it works for myself, from Linux to 
Linux, Windows to Linux. From the multiple 'fruit' lines, it is probably 
a good guess that you are using a Mac OS, so have you considered that 
this may in fact be a Mac problem ?
