[Bug 1711212] Re: smbclient fails to get shares from Mac OS X smb server

[rduke15]

Possibly a clue: when mounting manually with mount -t cifs I need to add
the nounix option:

  mount -t cifs //host/share /mnt/tmp -o username=$user,password=$pass

gives "mount ... failed: Operation not supported"

When using

  mount -t cifs //host/share /mnt/tmp -o
username=$user,password=$pass,nounix

It works.

Title:
  smbclient fails to get shares from Mac OS X smb server

Status in samba package in Ubuntu:
  Expired

Bug description:
  In Ubuntu 16.04.2 LTS, smbclient 4.3.11 cannot list shares from Mac OS
  X smb servers.

  Windows machines can access these Mac shares, and smbclient can also
  get the list of shares from the Windows 7 and Windows 10 machines.

  The errors are "NTLMSSP packet check failed due to short signature (0
  bytes)!", "NTLMSSP NTLM2 packet check failed due to invalid
  signature!" and finally "NT_STATUS_ACCESS_DENIED"

      $ sudo smbclient -A ~/smb.creds -d 2 -L mac-os-x-host
      rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

  I then tried to upgrade smbclient to the version 4.4.5 from Ubuntu
  16.10, but still get the same result. The upgrade was difficult due to
  many dependencies, but this seems to have worked to upgrade (after
  downloading all these packages from the 16.10 repository:

      sudo dpkg -i Downloads/libreadline7_7.0-0ubuntu2_amd64.deb 
      sudo dpkg -i Downloads/samba-common_4.4.5+dfsg-2ubuntu5_all.deb 
      sudo dpkg -i Downloads/python-talloc_2.1.7-1_amd64.deb 
      sudo dpkg -i Downloads/libwbclient0_4.4.5+dfsg-2ubuntu5_amd64.deb 
      sudo dpkg -i Downloads/libgnutls30_3.5.3-5ubuntu1_i386.deb 
      sudo dpkg -i Downloads/libgnutls30_3.5.3-5ubuntu1_amd64.deb 
      sudo dpkg -i Downloads/samba-libs_4.4.5+dfsg-2ubuntu5_amd64.deb 
      sudo dpkg -i Downloads/smbclient_4.4.5+dfsg-2ubuntu5_amd64.deb 

      smbclient -V
          Version 4.4.5-Ubuntu

  But the error messages are still exactly the same.
