Abstract
Methods and systems for caching of remote server MAC authentication to enable fast roaming are provided. According to one embodiment, a wireless network controller of a wireless local area network (WLAN) receives an authentication request relating to a wireless client device from a wireless access point (AP) managed by the wireless network controller. It is determined whether a prior authentication result associated with the client is present in a cache of the controller. The client is permitted to access the WLAN via the AP when the prior authentication result is present and indicates the client was previously successfully authenticated. The authentication request is issued to a remote authentication device associated with the WLAN to determine a current authentication status of the client. Responsive to receipt of the current authentication status, information regarding the current authentication status is stored by the controller within the cache.
