Hello,
we are using Confluence behind a BIG IP F5 loadbalancer and with Shibboleth as SSO provider. This setup works great, but now we have a problem with the companion app. The connection between the browser and the companion app works - even the correct app is started. But instead of the file we are getting the error message of our Identity Provider. So we need an option, to reauthenticate the companion app with our Identity Provider.
