I use Kubuntu but there shouldn't be any fundamental difference. I do
have Samba installed and fuse and gadmin-samba. After I have set up my
shared folders I always deactivate, reread and active in gadmin-samba.
Then it tells me that the inactive server is winbindd. To enable that
I found by trial and error that it requires a sudo winbindd in a
terminal.

Only after I have gone through this complicated routine can I browse
my local network. It seems like a lot of trouble and I'd welcome
suggestions for an easier way but it seems that most of the people
here don't use or want to be on a LAN.
