Network system as well as a method for controlling access from a first network component to at least one second network component

In a method for controlling access from a first network component to at least one second network component, a unique user identification for a user of the first network component is calculated by the first network component. A request created by the first network component on the basis of an order is transmitted with the unique user identification to the second network component. A rights checking instruction is created by the second network component on the basis of the unique user identification. The rights checking instruction is transmitted by the second network component to the first network component. Access for the user to the second network component is provisioned by the second network component when a transmitted result of a check indicates that the user is authorized for access to the second network component.
