The section you are looking at, lets you use miniOrange as SP so that you can log into the miniOrange console by authenticating with your IDP.
If you can let me know more about your usecase by answering the following questions, I can guide you further in order to achieve it.
How will your users initiate the login?
Will they first land at miniOrange, from where they will be redirected to the IDP for authentication? (SP-initiated)
Or will your users log into their IDP dashboard first, from where they can click on a application button to get logged into miniOrange? (IDP-initiated)
Why exactly do you want your users to perform SSO into the miniOrange dashboard?
Do you have any applications configured in miniOrange which you want the users to click and get logged into that application?
Any further details you can provide about your use case will me much appreciated.
