Configuring SAML with JumpCloud

1. Configure SAML 2.0 application on JumpCloud

Configure a new SAML 2.0 application with the following settings:

• Display Label: Recommend Sourcegraph, but could be anything you prefer.
• IdP Entity ID: Recommend JumpCloud, but could be anything you prefer.
• SP Entity ID: Sourcegraph
• ACS URL: https://sourcegraph.example.com/.auth/saml/acs
• SP Certificate: (remain unset)
• SAMLSubject NameID: email
• SAMLSubject NameID Format: urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
• Signature Algorithm: RSA-SHA256
• Sign Assertion: true (checked)
• Default RelayState: (remain unset)
• IdP-Initiated URL: (remain unset)
• Declare Redirect Endpoint: false (unchecked)
• IdP URL: Recommend https://sso.jumpcloud.com/saml2/sourcegraph, but could be anything you prefer.
• Attributes: (remain unset)

Once the application is created, look for a tiny link called export metadata on the bottom-right of the page. Click on the link and save the metadata file which will be used later.

2. Configure SAML authentication provider in Sourcegraph

Add a SAML auth provider with configID set to the SP Entity ID, and identityProviderMetadata set to the content of the metadata you saved in the previous section. Here is an example of what your site configuration should look like:

{
 // ...
 "externalURL": "https://sourcegraph.example.com",
 "auth.providers": [
    {
      "type": "saml",
      // This value must match the "SP Entity ID" of your JumpCloud application.
      "configID": "Sourcegraph",
      "serviceProviderIssuer": "Sourcegraph",
      // You can escape the metadata to a JSON string using a tool like https://json-escape-text.now.sh.
      // Please be noted it is an online tool and could leak or record your confidential information.
      "identityProviderMetadata": "<?xml version=\"1.0\" encoding=\"UTF-8\"?><md:EntityDescriptor xmlns:md=\"urn:oasis:names:tc:SAML:2.0:metadata\" entityID=\"JumpCloud\"><md:IDPSSODescriptor WantAuthnRequestsSigned=\"false\" protocolSupportEnumeration=\"urn:oasis:names:tc:SAML:2.0:protocol\"><md:KeyDescriptor use=\"signing\"><ds:KeyInfo xmlns:ds=\"http://www.w3.org/2000/09/xmldsig#\"><ds:X509Data><ds:X509Certificate>..."
    }
 ]
}
