Anyways, the point to be clarified that remains is -
In case of a connected resource, a new resource with the same resource
identifier is to be returned a <conflict/>, whereas in the case of an
active resource, a new resource with the same resource identifer is
recommended to be allowed to login, returning a <conflict/> to the old
resource.
