Kerberos auth for Microsoft Remote Desktop Services ??

Hi. I have the exact same question. I've set up APM as a oauth service provider to provide the users a rdp gateway webtop, and are successfully "authenticating" azuread users. I'm also successfully getting a kerberos ticket for the user via contrained delegation so the user are single-signed on to the rds web feed. But when users are starting the native rdp client the SSO stops. I would also like to get the kerberos-ticket sent to the session host. Did you solved this in any way?
