SAML Protocol support for node (only IdP for now)

SAML Protocol middleware to create SAMLP identity providers for node.js.

Installation

npm install samlp

Introduction

This middleware is meant to generate a valid SAML Protocol identity provider endpoint that speaks saml.

The idea is that you will use another mechanism to validate the user first.

The endpoint supports metadata as well in the url /FederationMetadata/2007-06/FederationMetadata.xml.

Usage

Options

Name	Description	Default
cert	public key used by this identity provider	REQUIRED
key	private key used by this identity provider	REQUIRED
getPostURL	get the url to post the token f(audience, samlRequestDom, req, callback)	REQUIRED
issuer	the name of the issuer of the token	REQUIRED
audience	the audience for the saml token	req.query.SAMLRequest.Issuer
getUserFromRequest	how to extract the user information from request	function(req) { return req.user; }
profileMapper	mapper to map users to claims (see PassportProfileMapper)	PassportProfileMapper
signatureAlgorithm	signature algorithm, options: rsa-sha1, rsa-sha256	'rsa-sha256'
digestAlgorithm	digest algorithm, options: sha1, sha256	'sha256'
RelayState	state of the auth process	```req.query.RelayState
sessionIndex	the index of a particular session between the principal identified by the subject and the authenticating authority	SessionIndex is not included
responseHandler	custom response handler for SAML response f(req, res, SAMLResponse)	HTML response that POSTS to postUrl

Add the middleware as follows:

app.get('/samlp', samlp.auth({
  issuer:     'the-issuer',
  cert:       fs.readFileSync(path.join(__dirname, 'some-cert.pem')),
  key:        fs.readFileSync(path.join(__dirname, 'some-cert.key')),
  getPostURL: function (wtrealm, wreply, req, callback) { 
                return cb( null, 'http://someurl.com')
              }
}));

SAML Protocol Metadata

This module also support generating SAML Protocol metadata (IDPSsoDescriptor):

app.get('/samlp/FederationMetadata/2007-06/FederationMetadata.xml', samlp.metadata({
  issuer:   'the-issuer',
  cert:     fs.readFileSync(path.join(__dirname, 'some-cert.pem')),
}));

It also accept two optionals parameters:

• profileMapper: a class implementing the profile mapper. This is used to render the claims type information (using the metadata property). See PassportProfileMapper for more information.
• endpointPath: this is the full path in your server to the auth route. By default the metadata handler uses the metadata request route without /FederationMetadata/2007..blabla.
