[Bug 1556740] Re: Unable to connect to share unless "Guess access" is checked

Mon Mar 14 05:42:23 UTC 2016

** Description changed:

  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 is confirmed the file /var/lib/samba/private/secrets.tdb exists on
  both server and client, and the permissions for this file have not been
  adjusted in anyway. It's the default setup after installing the samba
  package.
