rmdir bug?

[Lindeman, Andrew]

Samba Developers--

I have a share called pub.  In that share, there is a folder that I want to
block access to.  So, I chmoded it 0700 and chowned it root.  In my smb.conf
file, I set the "guest account" parameter to "netshare", an unprivialized
user.  I also set the "guest only" parameter to "yes"  No remote computer
can "cd" into the directory, but all can delete (rmdir) the folder.  The
folder is chmoded -rwx------ and root owns the file.  Is this a bug or my
misunderstanding?

Thank you
