I wanted to know if anyone has tried federated authentication with Sitecore Horizon?, I have a federated environment that enables users to login with Azure AD and Horizon isn't working (givesit gives 500 error) which I assume since its service host it doesn't know anything about my federation providers.
More details on the stack trace:
