We’ve managed to implement service provider with SPID authentication and tested successfully on demo environment here - https://demo.spid.gov.it/.
So next step, we need to test the solution with real identity providers (i.e. Poste, Sielte, Infocert …etc). The question is how can we get some testing users on real IdPs (Poste, Sielte and/or Infocert)?
There are no “testing users” for IdPs.
If any of you are italian citizens or foreign citizens living in Italy, you can request your SPID identities.
Otherwise, “Ambiente Demo” works as a real IDP and allows you to test several types of identities (natural person, legal person, etc)
I have built a SP to connect with IdP of demo environment at https://demo.spid.gov.it. They have given a list of test users. I am getting wrong credentials message most of the users listed. Is that not the list that we can try with? Appreciate any inputs.
