--------------------------------

I have no idea what the output means. It didn't go back to command 
prompt so I had to Ctrl+C.

I then restarted winbind but still showed "active (exiting)" and 
complained about the "mode" which I already set to "classic".
I then stopped the service and started it again and is running.(:o) I 
don't know what the command "winbindd -F -d10 -s" did
or whether it fixed the problem but is working now. :)

Thanks a lot Loui
