Resolution
At present, there is no way to configure IP filters on the WLSE. However, one can authenticate users using a local authentication module or using an external server to do RADIUS or TACACS+ authentication. Once you have selected and configured a module, all authentication transactions are performed by the authentication service associated with that module. Users log in with the user ID and password associated with the current authentication module. Note that you must create all user roles on the local authentication module.
