SmbK4 can't connect

I installed Smb4K and ran it. When I attempted to attach to my Mac (Samba) server, I get this error: smbmnt must be installed suid root for direct user mounts (1000,1000) smbmnt failed: 1 Here's the command I entered to fix it: sudo chmod a+s /usr/bin/smbmnt a+s means "set the suid for all users." That did it.
