[Satosa-dev] SATOSA and step-up with Duo or the like

Hi, I know it has been talked about as "doable", but has anybody already deployed SATOSA with a response microservice that implements a "step-up" flow to leverage a second factor (like Duo) when the authenticating IdP does not assert that MFA was used? If so, are you considering sharing it and/or contributing it to the code base? If not, but you are considering such an implementation/deployment, can you indicate if you are interested in collaborating on the development and testing? Thanks, Scott K
