We want to allow our customers to sign in via SSO (they use Azure AD). After login to our site, we would like to be able to redirect our users to a 3rd-party partner to login under the same credentials that the user used for our site. Let's say that our customer is FooCompany and all their users login with username@foo.com
However, because of how our partner operates, all users for FooCompany (e.g. user1@foo.com, user2@foo.com, etc.) must use the same user on our partner's site. What is the best way of setting this up using SSO standards?
