node bin/server.js --iss {issuer} --idpSsoUrl {url} --idpCert="$SAML_IDP_CERT" --spCert="$SAML_SP_CERT" --spKey="$SAML_SP_KEY"
The SAML 2.0 protocol is specified with --protocol samlp (default)
The IdP settings needed for federation can be auto-configured via IdP SAML Metadata. If IdP SAML metadata is not available you can manually specify service endpoints, binding, and signing credentials.
If you need an IdP to test with, use Simple Identity Provider (IdP) for SAML 2.0 for all your end-to-end SAML 2.0 Web Browser SSO flows!
| Endpoints | Argument | Default |
|---|---|---|
| SSO Service URL | idpSsoUrl |
|
| SSO Service Binding | idpSsoBinding |
urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect |
| SLO Service URL | idpSloUrl |
|
| SLO Service Binding | idpSloBinding |
urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect |
You must specify the public key certificate with the idpCert or SHA1 thumbprint with idpThumbprint argument to validate the SAMLResponse message from the IdP.
You need to create a SAML trust in your SAML IdP for the SP web app. The following settings are required and can be customized via command-line arguments or within the /settings page.
The default SP audience is urn:example:sp. You can change this with the --aud argument.
The Service Provider only supports the HTTP-POST binding for the Assertion Consumer Service
| Service | Binding | URL |
|---|---|---|
| Assertion Consumer Service | HTTP-POST | http://localhost:port/saml/sso (Default) |
| Single Logout Service | HTTP-POST | http://localhost:port/saml/slo |
You can specify additional endpoints (relative paths) for the Assertion Consumer Service with the acsUrls argument. The first ACS URL in the array (e.g. acsUrls[0]) is used by default for AuthnRequests. You can select any configured ACS URL for requests with the /login?acsUrl=/path query param or by going to the settings page in the SP and selecting the default ACS URL.
You should generate a self-signed certificate for the SP.
openssl req -x509 -new -newkey rsa:2048 -nodes -subj '/C=US/ST=California/L=San Francisco/O=JankyCo/CN=Test Service Provider' -keyout /config/sp-key.pem -out /config/sp-cert.pem -days 7300
This key-pair will be used to sign SAML AuthnRequest and LogoutRequest messages generated by the Service Provider. You can disable AuthnRequest message signatures with the signAuthnRequests argument. LogoutRequest messages always require signatures.
The Service Provider uses the same key-pair for signatures and decryption. Use the same signing public key certificate to encrypt SAML assertion in the IdP.
Service Provider SAML metadata is available on http://localhost:port/metadata
The WS-Federation protocol is specified with --protocol wsfed
The IdP settings needed for federation can be auto-configured via IdP Metadata. If IdP metadata is not available you can manually specify service endpoints, binding, and signing credentials.
| Endpoints | Argument | Default |
|---|---|---|
| IdP Passive Requestor Endpoint | idpSsoUrl |
You must specify the public key certificate with the idpCert or SHA1 thumbprint with idpThumbprint argument to validate the SAML 2.0 security token returned from the IdP.
You need to create a federation trust in your IdP/STS for the RP web app. The following settings are required and can be customized via command-line arguments or within the /settings page.
The default RP realm/audience is urn:example:sp. You can change this with the --aud argument.
The Relying Party only supports the HTTP-POST binding for the Security Token Response Endpoint
| Service | Binding | URL |
|---|---|---|
| Security Token Response Endpoint | HTTP-POST | http://localhost:port/saml/sso |
Use the same signing public key certificate to encrypt SAML assertion in the IdP.
Relying Party SAML metadata is available on http://localhost:port/metadata
You can customize the port and optionally provide a TLS/SSL certificate for the Service Provider to enable HTTPS
The web app hosts the following URL routes:
| Route | Description |
|---|---|
/profile |
Displays the user profile for the authenticated user |
/login |
Initiates a SSO request to the IdP |
/logout |
Attempts to logout via SAML SLO if configured otherwise just destroys the user's active session |
/settings |
Service Providers settings |
/saml/sso |
SSO Assertion Consumer Service / Security Token Service Response Passive Endpoint |
/saml/slo |
SLO endpoint |
/metadata |
Service Provider/Relying Party Metadata endpoint |
Specify the https argument to enable TLS along with public key certificate and private key in PEM format
node bin/server.js --https --httpsCert {cert} --httpsKey {key}
