Azure AD B2C and ADFS as SAML IdP. Code example?

Question

I want users of my application authenticated in a couple of on-premises ADFS servers.

I setup Azure B2C working together with ADFS as SAML identity provider.

The setup process is described here in MS official docs https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-custom-setup-adfs2016-idp

That was complicated, but now my custom policy B2C_1A_SignUpOrSignIn works, in meaning that it redirects to B2C login page with buttons first, then I click a button and system redirects to ADFS login page, where asks users for login and passwords.

But how to integrate it with a .NET or Node.js application? Any code examples?

Answer 1

Samples for different platforms can be found at Azure Active Directory B2C code samples.

If a sample application references a built-in policy, such as "B2C_1_SignUpOrSignIn", then you must replace this with your custom policy.
