Integrate Ubuntu 14.04 (Trusty Tahr) to Zentyal PDC (Primary Domain Controller) – Part 7

From my previous post about integrating Ubuntu 13.10 to Zentyal PDC Active Directory things have changed for some software packages once the release of Ubuntu 14.04, codename Trusty Tahr, and seems like Ubuntu developers had dropped support for ???likewise-open??? package which did an excellent job of integrating Ubuntu to Windows Active Directory in just a few moves and clicks.
