Hoteling Guest & Hoteling Host

“Hoteling” consists of two separate services: “Hoteling Host” and “Hoteling Guest”. The first service “Hoteling Host” is used for marking a certain user as a host of a system and allows other users of the “Hoteling Guest” service to use their profile configuration on the system of the main user. The second service “Hoteling Guest” is used in order to give the user an opportunity to work from one’s profile on the set which has the main user assigned already by the “Hoteling” service. This function is usually used for temporary workers or those who do not have an assigned work station.
