I'm having a problem getting SSO to work from outside my organisation. We use Windows IIS as a proxy server (https://kb.paessler.com/en/topic/44613-using-windows-iis-as-ssl-proxy-for-prtg) for all our applications which for PRTG only seems to work with Active directory integration.
When i select the IP address as Callback URL the button Login with SSO comes available but i get an Azure error stating that the reply URL is unkown. When i add the IP address as Redirect URL in Azure the login works but im redirected to the internal IP which is not reachable from outside.
Is there a manual for the right way to configure this? I only want to use SSO. Also, is SSO supported for the desktop and android app? I'm missing the SSO sign in button there.
