[Fiware-tech-help] [Chp - IoT][IDAS] Fix errors on neoidas-bd rpm package

[David Muriel]

The neoidas-bd rpm package currently available has some errors that
need to be fixed:

* Set the user and group of files during package creation:

  The files on the package have the group set to "idas" and the user
set to "manager", which may not exist when installing the package,
raising the following error:

    warning: group idas does not exist - using root
    warning: user manager does not exist - using root

  This can be fixed when building the rpm package by using the %attr
and %defattr directives on the %files section of the package spec
file.  If the user and group must exist, state on the installation
guide the necessary commands to create them.
