Azure AD B2C newbie here. I have a Single Page Application hosted in Azure & it uses Azure Functions. I want to allow users in many organisations to login to my application using their existing corporate email address, & authenticated in their company's Azure AD, which I have no access to.
For instance I want people in company Contoso to access my Azure SPA by logging in with their existing Contoso email addresses "[email protected]". Authentication takes place in Contoso's Azure AD.
Do I use the Azure AD B2C Identity Experience Framework & Custom Policy for this? Any guidance would be helpful.
