Hi all! 🙂 Is it possible to authenticate the Perspective session on an (wan-offline) Edge gateway, trough the IDP defined on a central Ignition server? The central is configured to use Entra ID, and this works well on the central Perspective sessions. ---

An IdP must be reachable directly by the client browser. If you can configure a proxy for IdP URL, you should be able to make it work. But be aware that you won't be able to authenticate at the Edge if the WAN is down. ---

Hi Phil, thanks for replying! We could do this by adding Entra as a Identify provider on the Edge as well, and the gateway will need a proxy or wan access to the IdP URL. Is that a good summary, there is no way to do this within the gateway network and central server? 🙂
