In my current environment, we are operating in a master/standby configuration. For the guest wireless, we use a captive portal authentication method. Since all APs are connected to the master controller, when a user moves from AP to AP, there are no issues with authentication.
We are going to move to a Master/Local1/Local2 controller configuration where some APs will be connected to the Local1 controller and other APs will be connected to the Local2 controller. My question involves this scenario.
1: User is associated with AP1 which is connected to controller Local1.
2: User authenticates to the captive portal. Local1 knows that user is authenticated.
3: User moves to a different location and asosciates with AP2 which is conencted to controller Local2.
Question is, does controller Local2 know that the user has already authenticated via the captive portal, or will the user be requred to authenticate again? Does the master controller keep track of authenticated users?
FYI, all the controllers will be layer2 adjacent on all VLANs
Thanks,
Robert
