I want to prevent anonymous/non-domain users from see the available drive
shares on my samba primary domain controller.  A Windows NT4 server on the
network provides this functionality (i.e. I can only see the share
listings if I provide username and password "smbclient -L //nt4pdc -U
username")

I was very hopeful with this John, but it did not seem to work.  I added
this line to my smb.conf, testparm said everything was fine, I reloaded
samba, stopped and restarted samba, and even tried from a totally
different gnu/linux systems not even associated with the domain (machine
or user), and it still enumerated the file shares on my samba pdc.

Is there any other configuration options to prevent this?
