PingGateway 2024.11

Signed/encrypted assertions

  1. Set up the example in Unsigned/unencrypted assertions.

  2. Set up the SAML keystore:

    1. Find the values of AM’s default SAML keypass and storepass:

      $ more /path/to/am/secrets/default/.keypass
$ more /path/to/am/secrets/default/.storepass

    2. Copy the SAML keystore from the AM configuration to PingGateway:

      $ cp /path/to/am/secrets/keystores/keystore.jceks /path/to/ig/secrets/keystore.jceks
      Legacy keystore types such as JKS and JCEKS are supported but aren’t secure. Consider using the PKCS#12 keystore type.

  3. Configure the Fedlet in PingGateway:

    1. In FederationConfig.properties, make the following changes:

      1. Delete the following lines:

        • com.sun.identity.saml.xmlsig.keystore=%BASE_DIR%/security/keystores/keystore.jks

        • com.sun.identity.saml.xmlsig.storepass=%BASE_DIR%/.storepass

        • com.sun.identity.saml.xmlsig.keypass=%BASE_DIR%/.keypass

        • com.sun.identity.saml.xmlsig.certalias=test

        • com.sun.identity.saml.xmlsig.storetype=JKS

        • am.encryption.pwd=@AM_ENC_PWD@

      2. Add the following line:

        org.forgerock.openam.saml2.credential.resolver.class=org.forgerock.openig.handler.saml.SecretsSaml2CredentialResolver

        This class is responsible for resolving secrets and supplying credentials.

        Be sure to leave no space at the end of the line.

    2. In sp.xml, make the following changes:

      1. Change AuthnRequestsSigned="false" to AuthnRequestsSigned="true".

      2. Add the following KeyDescriptor just before </SPSSODescriptor>

                <KeyDescriptor use="signing">
            <ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#" >
                <ds:X509Data>
                    <ds:X509Certificate>

                    </ds:X509Certificate>
                </ds:X509Data>
            </ds:KeyInfo>
        </KeyDescriptor>
    </SPSSODescriptor>

      3. Copy the value of the signing certificate from idp.xml to this file:

        <KeyDescriptor use="signing">
  <ds:KeyInfo>
    <ds:X509Data>
      <ds:X509Certificate>

        MII...zA6

      </ds:X509Certificate>

        This is the public key used for signing so that the IDP can verify request signatures.

  4. Replace the remote service provider in AM:

    1. Select Applications > Federation > Entity Providers, and remove the sp entity provider.

    2. Drag in or import the new sp.xml updated in the previous step.

    3. Select Circles of Trust: Circle of Trust.

  5. Set up PingGateway:

    1. In the PingGateway configuration, set environment variables for the following secrets, and then restart PingGateway:

      $ export KEYSTORE_SECRET_ID='a2V5c3RvcmU='
$ export SAML_KEYSTORE_STOREPASS_SECRET_ID='base64-encoded value of the SAML storepass'
$ export SAML_KEYSTORE_KEYPASS_SECRET_ID='base64-encoded value of the SAML keypass'

      The passwords are retrieved by a SystemAndEnvSecretStore, and must be base64-encoded.

    2. Remove saml-handler.json from the configuration, and add the following route, replacing the path to keystore.jceks with your path:

      • Linux

      • Windows

      $HOME/.openig/config/routes/saml-handler-secure.json
      %appdata%\OpenIG\config\routes\saml-handler-secure.json
      {
  "name": "saml-handler-secure",
  "condition": "${find(request.uri.path, '^/saml')}",
  "heap": [
    {
      "name": "SystemAndEnvSecretStore-1",
      "type": "SystemAndEnvSecretStore"
    },
    {
      "name": "KeyStoreSecretStore-1",
      "type" : "KeyStoreSecretStore",
      "config" : {
        "file" : "/path/to/ig/keystore.jceks",
        "storeType" : "jceks",
        "storePasswordSecretId" : "saml.keystore.storepass.secret.id",
        "entryPasswordSecretId" : "saml.keystore.keypass.secret.id",
        "secretsProvider" : "SystemAndEnvSecretStore-1",
        "mappings" : [ {
          "secretId" : "sp.signing.sp",
          "aliases" : [ "rsajwtsigningkey" ]
        }, {
          "secretId" : "sp.decryption.sp",
          "aliases" : [ "test" ]
        } ]
      }
    }
  ],
  "handler": {
    "type": "SamlFederationHandler",
    "config": {
      "useOriginalUri": true,
      "assertionMapping": {
        "username": "cn",
        "password": "sn"
      },
      "subjectMapping": "sp-subject-name",
      "redirectURI": "/home/federate",
      "secretsProvider" : "KeyStoreSecretStore-1"
    }
  }
}

      Notice the following features of the route compared to saml-handler.json:

      • The SamlFederationHandler refers to the KeyStoreSecretStore to provide the keys for the signed and encrypted SAML assertions.

      • The secret IDs, sp.signing.sp and sp.decryption.sp, follow a naming convention based on the name of the service provider, sp.

      • The alias for the signing key corresponds to the PEM in keystore.jceks.

    3. Restart PingGateway.

  6. Test the setup:

    1. Log out of AM, and test the setup with the following links:

    2. Log in to AM with username demo and password Ch4ng31t.

      PingGateway returns the response page showing that the the demo user has logged in.
