Light weight AP at site A, connects to a remote controller at site B. Is there a way to authenticate user locally at site A?
Thats a loaded question without more detail its hard to say ..
- What equipment are you using ..
If the adopted AP has a option of running RADIUS, then we can run RADIUS server on the local AP and Authenticate user locally. Fat APs can be adopted by the controller and many vendors provide the option of authenticating user locally or from the controller.
Thats making assumptions. Without knowing the equipment being used its difficult to say.
