[Bug 1797944] Re: sudoers entries with FQDN are ignored on Ubuntu 14.04

[Oleg Gumenyuk]

** Description changed:

  Here is the short example of /etc/sudoers in order to reproduce the issue that if host is defined as FQDN then such string is skipped on Ubuntu 14.04. The following sudo is installed on the host "1.8.9p5-1ubuntu1.4  amd64"
  ~~~~~~~~~~~~~
