Thanks for your answer. I understand SSO is out of scope of framasoft, as well explained before.
Application orchestration is for me a completely different story as it aims at integrating information and processes of different providers, different companies, different systems,… and making it all work together for more users benefits. This integration possibility is for me a cornerstone in adopting OpenSource instead of proprietary system, and a good argument against lock-in in closed system.
I hope framasoft can help push this a bit forward too, by trying to select and promote services accordingly.
