Handle the Identity provider side of SAML using Node.js

Question

I need to implement an Identity provider service (using node.js) that should be able to.

• Get, validate and parse (using private key and cretificate) the authentication request from SP example

• If everything is valid, respond with a signed XML response example

  Is there a tool in node.js that can handle the IdP side of SAML protocol. i'm familiar with samlify, saml2, passport-saml, and all of them seem to handle the Service provider side of the protocol.

---

If the packages mentioned here can serve to my needs, could you specify how exactly they handle this. Any other directions and/or hints may be helpful.

Thanks

Answer 1

I have used samlify to make my existing node js application as identity provider to third party service provider.

It has many configuration options. Intially it took time to successfully implement.

Answer 2

This is what my research say about this modules .

Passport-saml - Provider service provider only

Saml2-js - Provide service provider

Samlify - Idp in experimental phase , You can check idp implementation here. https://github.com/tngan/samlify/blob/f2b6a2f8c36dc0ff887d0442c48cd0f2c0a4a778/examples

Node-samlp - IDP which provide saml assertion but user authorization we need to do our own

Saml-idp - It says IDP we can create but again it refer to online IDP
