Public bug reported: What is expected to happen:
On the Ubuntu 16.04 samba server with hostname HOSTNAME log in as first user created when installing USERNAME with password PASSWORD > create a new folder via nautilus (no gksudo) called test > secondary click test > Properties > tab Local Network Share > check "Share this folder" > Share name: test > other checkboxes unchecked > click button "Create Share" On another Ubuntu 16.04 client click Places > Network > Windows Network > WORKGROUP > HOSTNAME > test > in the new connection window it notes at top: Password required for share test on HOSTNAME to the right of "Connect As" click radio button "Registered User" > put in Username field USERNAME > put in field Domain WORKGROUP > put in field Password PASSWORD > click radio button Forget password immediately > Connect and it does so. What happens instead is the connection window comes back up, but this time the "Connect As" radio button is now on Anonymous (Default) and everything else is grayed out. Hitting the X to close the window intermittently shows: Unable to access location Failed to mount Windows share: Invalid argument The only way to allow the share to be connected is if one clicks on the server the checkbox "Guest access (for people without a user account)". This prevents easily implementing secure and authenticated data transfers between server and client.

It's the default setup after installing the samba package.
