Many public hotspots operate roaming partnerships allowing customers of Orange, T-Mobile, OpenZone access using their prepaid hotspot accounts.
I’m just starting to think how this would work in principle on MT hotspot…
If we had access to their Radius servers and add these to the Radius servers list on the MT - will the login try each Radius in turn until it finds a matching username and password?
Usually you would configure your RADIUS server to forward certain requests (like based on a prefix) to other RADIUS servers. That’s a feature called Proxy-RADIUS.
So (fictive example) if a user of your hotspot would enter “joe@orange.com” as username, your RADIUS server could be configured to forward all auth request for usernames ending with “@orange.com” to a RADIUS server from Orange.
Your RADIUS server would just “forward” the answer to your hotspot.
