SAML Protocol middleware to create SAMLP identity providers for node.js.
npm install samlp
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.
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(SAMLResponse, options, req, res, next) | 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){returncallback(null,'http://someurl.com')}}));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.
