1. Navigate to the <AS_HOME>/repository/conf/security/authenticators.xml file. 

2. Open the authenticators.xml file and set the "disabled" attribute value to "false" for the SAML2SSOAuthenticator configuration.

   When the cluster is hosted on the cloud or on a remote server, the IdentityProviderSSOServiceURL tag must be changed in the <PRODUCT_HOME>/repository/conf/security/authenticators.xml file. This should point to the host URL of the load balancer of the cluster. This is done because the authentication is done by the WSO2 Identity Server cluster and the load balancer will decide where the authentication request is sent to. From WSO2 Identity Server 5.0.0 onwards, there are different SAML endpoints for each tenant. If the service provider calls the identity provider's SAML endpoint URL as https://is.com:9443/samlsso?tenantDomain=foo.com or the issuer name is appended with @<TenantDomain> like travelocity.com@foo.com, the SAML requests are directed to the foo.com tenant. The VerifySignatureWithUserDomain property is used to make the most recent Carbon-based products switch behaviour to expect SAML responses in the previous way. I.e., if this is set as true, it means that the SAML response is verified with the tenant's key that the authenticated user is belongs to. If it is set to false it means that the SAML response is verified with the tenant's key to which the SAML request is directed to. This can be set in the <PRODUCT_HOME>/repository/conf/security/authenticators.xml file. Code Block language xml <VerifySignatureWithUserDomain>true</VerifySignatureWithUserDomain>

1. Follow the exact same steps done for the WSO2 Application Server and enable the SAML2SSOAuthenticator in the <ESB_HOME>/repository/conf/security/authenticators.xml file.

2. Change the ServiceProviderID. This ID is used by the Identity Server to identify the ESB's requests. Change this value to carbonServer2.

1. Download the WSO2 Identity Server from here.
2. Extract the .zip file.
3. Open a terminal and navigate to the <IS_HOME>/bin folder.
4. Start the Identity Server using the wso2server.sh file in Unix or wso2server.bat file in Windows.
5. Once the server is started, visit the following URL: https://localhost:9443/carbon/
6. Sign in to the WSO2 Identity Server. Enter your username and password to log on to the Management Console. 
7. Navigate to the Main menu to access the Identity menu. Click Add under Service Providers.
    

8. Fill in the Service Provider Name and provide a brief Description of the service provider in the resulting screen. If the service provider configuration is used by tenants as well, you must select the SaaS Application checkbox.

   Tip

   Tip: By default, the SaaS Application checkbox is disabled, which means the web application is not shared among tenants so only users in the current tenant (the one you use to define the service provider) will be allowed to log into the web application. Alternatively, if you enabled the SaaS Application checkbox, that means this web application is shared among tenants so users from any tenant will be allowed to log into the web application. For example, if there are three tenants, namely TA, TB and TC and the service provider is registered and configured only in TA. If the SaaS Application configuration is disabled, only users in TA are able to log into the web application. If the SaaS Application configuration is enabled, all TA, TB, TC users are able to log into the web application.

9. Expand the SAML2 Web SSO Configuration under Inbound Authentication Configuration.
    
10. Click Configure. Fill in the form that appears.
    
11. Fill up this page with the following configurations. You must register different service providers for WSO2 Application Server, WSO2 ESB and WSO2 Governance Registry.
    

    1. Use the following configurations for WSO2 Application Server and add them to the relevant sections in the New Service Provider screen:

       Panel
       Issuer: carbonServer Assertion Consumer URL: https://localhost:9444/acs Use fully qualified username in the NameID Enable Response Signing Enable Assertion Signing Enable Single Logout

    2. Use the following values to register the WSO2 ESB:

       Panel
       Issuer : carbonServer2 Assertion Consumer URL : https://localhost:9445/acs Use fully qualified username in the NameID Enable Response Signing Enable Assertion Signing Enable Single Logout

    3. Use the following values to register the WSO2 Governance Registry.

       Panel
       Issuer : carbonServer3 Assertion Consumer URL : https://localhost:9446/acs Use fully qualified username in the NameID Enable Response Signing Enable Assertion Signing Enable Single Logout

    4. Make a note of the following when you are using tenant configurations. This can be done in all the WSO2 Carbon servers.

       Note
       title Additional configurations
       If you need to sign the SAML response using an authenticated user's tenant keystore, please add the following configuration. (By default, the response is signed using the certificate that belongs to the tenant where the service provider is registered). This property must be added if the SAML authenticator version in the WSO2 Carbon products that you are using is 4.2.2 or higher (org.wso2.carbon.identity.authenticator.saml2.sso_4.2.2.jar). Add the <UseAuthenticatedUserDomainCrypto> property available in the <IS_HOME>/repository/conf/identity.xml file as shown below. Code Block language xml <SSOService> ... <UseAuthenticatedUserDomainCrypto>true</UseAuthenticatedUserDomainCrypto> </SSOService> The above configuration is an alternative to the VerifySignatureWithUserDomain property in the <PRODUCT_HOME>/repository/conf/security/authenticators.xml file.

12. Click Register to save the values and register each service provider created.
