Warn user if an ID range with incorrect size was created
    
    IPA 3.0 introduced range ID objects in replicated space which specify
    a range of IDs assigned via DNA plugin. ipa-ldap-updater generates the
    default ID range which should correspond with IDs assigned to IPA
    users.
    
    However, since correct range size is not known, we should at least
    warn that a range with invalid size was created so that user can
    amend it.
