1. Sign in to the API Manager's management console ( https://localhost:9443/carbon ) using admin/admin credentials and select Add under Identity Providers menu in the Main menu. 

   Note
   If you are using a tenant to create the Identity Provider, use the credentials of tenant admin to log into the API Manager's Management Console.

   

2. Provide the following values to configure the IdP:
   
   • Under Basic Information 
     
     • Identity Provider Name: Enter a unique name for IdP

     • Identity Provider Public Certificate:   The certificate used to sign the SAML assertion.  Export the public certificate of WSO2 IS and import it here. 

       Alternatively, you can create a self-signed certificate and then export it as a .cer file using the following commands: 

       Code Block
       keytool -genkey -alias wookie -keyalg RSA -keystore wookieKeystore.jks -keysize 4096 keytool -v -export -file keystore1.cer -keystore keystore1.jks -alias keystore1

     • Alias: Give the name of the alias if the Identity Provider identifies this token endpoint by an alias. e.g., https://localhost:9443/oauth2/token
     • Under Federated Authenticators -> SAML2 Web SSO Configuration

     • Enable SAML2 Web SSO: true
       

     • Identity Provider Entity Id: The SAML2 issuer name specified when generating the assertion token, which contains the unique identifier of the IDP. You give this name when configuring the SP.

     • Service Provider Entity Id: Issuer name given when configuring the SP

     • SSO URL: Enter the IDP's SAML2 Web SSO URL value. E.g., https://localhost:9444/samlsso/ if you have offset the default port, which is 9443.

       Note
       If you are in tenant mode, append the tenant domain to the SSO URL as a query parameter as below. https://localhost:9443/samlsso?tenantDomain=<tenantDomain>

    Next, let's register a service provider.
3. Log in to the management console of the Identity Server and select Add under Service Providers menu in the Main menu.
   
4. Choose to edit the service provider that you just registered and select SAML2 Web SSO Configuration.
   
5. Provide the following values to configure the SP and click Update.
   
   • Issuer: Give any name
   • Assertion Consumer URL:  The URL to which the IdP sends the SAML response (e.g., https://localhost:9443/store/jagg/jaggery_acs.jag).
   • Enable Response Signing: true
   • Enable Assertion Signing: true
   • Enable Audience Restriction: true
   • Audience: URL of the token API (e.g., https://localhost:9443/oauth2/token).

   
   Let's see how to get a signed SAML2 token (encoded assertion value) when authenticating against a SAML2 IdP. With the authentication request, you pass attributes such as the SAML2 issuer name, token endpoint and the restricted audience. In this guide, we use a command-line client program developed by WSO2 to create the 64-bit, URL-encoded SAML assertion. 

...

1. Combine the consumer key and consumer secret keys as  consumer-key:consumer-secret. Encode the combined string using base64 (http://base64encode.org). Here's an example consumer key and secret combination: wU62DjlyDBnq87GlBwplfqvmAbAa:ksdSdoefDDP7wpaElfqvmjDue.
   
   Let's create a SAML2 assertion using the same command-line client that you used in the previous section.
2. Download the command-line too from here and extract the ZIP file.

3. Go to the extracted folder using the command line and execute the following command. We assume that both the client and the API Gateway run on the same server. Therefore, the Token API URL is  https://localhost:8243/token.

   The arguments are as follows:

   • <Identity_Provider_Entity_Id> - This is the value of the saml:Issuer, which is a unique identifier of the identity provider.

   • <saml-subject> - This is the value of the name ID, which is found in the saml:Subject -> saml:NameId

   • <saml-recipient> - This is the value of the subject confirmation data recipient, which is found in the saml:Subject -> saml:SubjectConfirmation> saml:SubjectConfirmationData.Recipient

   • <saml-audience> - This is the value that is added to the saml:AudienceRestriction element of the token. This argument can take multiple values separated by commas. Each value is added as a saml:Audience element within saml:AudienceRestriction.

   • <Identity_Provider_JKS_file> - Pointer to the Java Key Store (JKS) file to be used for credentials.

   • <Identity_Provider_JKS_password> - The JKS password.
   • <Identity_Provider_certificate_alias> - The alias of the public certificate.
   • <Identity_Provider_private_key_password> - The password of the private key that is used for signing.

   This commend returns a SAML2 assertion XML string and a base64-URL encoded assertion XML string. 

4. Access the Token API using a REST client such as curl. For example, the following Curl command generates an access token and a refresh token. You can use the refresh token at the time a token is renewed. 

   Code Block
   curl -k -d "grant_type=urn:ietf:params:oauth:grant-type:saml2-bearer&assertion=<base64-URL_encoded_assertion>&scope=PRODUCTION" -H "Authorization: Basic <base64_encoded_consumer-key:consumer-secret>" -H "Content-Type: application/x-www-form-urlencoded" https://localhost:8243/token

   Note
   Note that the Registered Users for Application statistics takes the number of users shared each of the Application. And for the users to be counted in the statistics, they should have to generate access tokens using Password Grant type.
