What does the local standalone switch do in the SSID settings in the context of the GUI

Hello All,

I have been racking my brain trying to figure out what the Local Standalone switch does in the Fortigate GUI for SSIDs utilizing the bridge network setting. I have gotten just the local authentication to work and understand its purpose. I can enable Local Standalone, but it appears to do nothing differently than having just local authentication selected. Do any of you have a use case for when you would select local standalone; or what the parameters would be to make this work. Thanks!
