In a first embodiment, the stress signal contains the user and/or the user group, the assignment of which is to be changed in the identifier table, and the identifier which is to be assigned to the user and/or the user group. In this embodiment, the stress routine can be executed in such a way that in the step of evaluating the stress signal, the user and/or the user group and the identifier are read from the stress signal. In a subsequent step, the entry in the identifier table is changed and the identification in the identifier table is assigned to the user and/or the user group. Before this step is conducted, the stress routine can check whether a locking attribute is assigned to the existing assignment of an identifier to a user or a user group, which is now to be changed. If a locking attribute is assigned to the existing assignment of an identifier to a user or a user group that is now to be changed, the entry in the identifier table is not changed and the identifier in the identifier table is not assigned to the user and/or the user group. In such a case, an error signal can be generated by the server. Alternatively, when a locking attribute is recognized, it can be checked whether the user who initiated the change has special authorization, for example an administrator within the user group. If the user has special authorization that authorizes him to make a change despite the locking attribute, the changes will be made.
