Network and wireless LAN authentication method used therein
First Claim
1. A network which comprises a first wireless LAN (Local Area Network) serving as a master of a wireless LAN management system and a second wireless LAN serving as a slave of the wireless LAN management system and which includes an authentication server for authenticating a wireless LAN terminal and a management server for performing management control in the network of the management server in each of the first and second wireless LANs, wherein the management server of the first wireless LAN comprises:
- means for integrally managing the authentication registration data in which information related to a wireless LAN terminal to be authenticated and registered is described; and
means for sending the integrally managed authentication registration data to the management server of the second wireless LAN, and wherein each of the management servers comprises an authentication table which is searched by the authentication server to check whether authentication of the wireless LAN terminal is permitted or not and which includes information of the wireless LAN terminals of all the wireless LANs.

Abstract
It is an object of the present invention to provide a network which can be connected to the network without making a management operation difficult even when a wireless LAN terminal moves. In a plurality of wireless LANs in which authentication servers are arranged, when authentication information of the wireless LAN serving as a slave is changed, the contents of the change are noticed to a wireless LAN serving as a master, and the changed authentication information is automatically sent from a management server of the wireless LAN serving as a master to a management server of the wireless LAN. The management server writes the sent authentication information in an authentication table of an authentication server.
