I tried to play with system tests and discovered that they some suits are always failing at my side and that fail seems to be related to test preparation procedure:

  # add_ldap_provider:
    * Copy /tmp/dchaplyg/tmpVIWROd to lago-basic-suite-master-engine:/tmp/dchaplyg/tmpVIWROd:
    * Copy /tmp/dchaplyg/tmpVIWROd to lago-basic-suite-master-engine:/tmp/dchaplyg/tmpVIWROd: ERROR (in 0:00:00)
