I am not particularly sure of the correct question to ask, so I apologize in advance if the question appears slightly vague.
I am looking to learn concepts and then implement the solution.
I have an Azure AD tenant, and an application within it (it was created with App registrations experience). We have set up login, callback, etc previously and it works.
Now we've been approached by a customer to enable login for their users into our application, using their organization's Azure AD SSO. I have browsed all the concepts and I think I have to enable Azure AD B2B, I might be wrong here.
I am not aware of the conversations that took place with the customer before it reached me, but they have shared an XML and certificate over email that reached me, asking me to integrate into our application.
This is where I am puzzled, as I am not sure about what needs to be done. Kindly help me go in the right direction.
