Enabling SAML as an identity provider

Jazz™ Authorization Server supports Security Assertion Markup Language (SAML) web browser single sign-on (SSO) in the WebSphere Liberty, which enables web applications to delegate user authentication to a SAML identity provider instead of a configured user registry.

Before you begin

If you have not already done so, copy the files in the JazzAuthServer_install_dir/wlp/usr/servers/jazzop/defaults directory up one level to the jazzop directory as described in Managing users on Jazz Authorization Server.
Restriction: SAML is supported for authentication through Jazz Authorization Server. Because in the Liberty server the user group information is coming from the user registry associated with Jazz Authorization Server, a user registry to map user groups to security roles is required.

About this task

Starting in version 6.0.1, Jazz Authorization Server supports SAML web browser SSO in the Liberty profile. SAML is an OASIS open standard for representing and exchanging user identity, authentication, and attribute information. A SAML assertion is an XML formatted token that is used to transfer user identity and attribute information from the identity provider (IdP) of a user to a trusted service provider (SP) as part of completing an SSO request. For more information, see SAML web single sign-on.

To configure the Jazz Authorization Server as a SAML SSO service provider (SP), complete the next steps.


  1. Enable the Jazz Authorization Server to support SAML 2.0.
    1. Open the JazzAuthServer_install_dir/wlp/usr/servers/jazzop/server.xml file in an editor.
    2. Locate the SAML xml section and follow the instructions between the <!-- SAML> and <!-- end of SAML> comments to enable the SAML and SSL features.
    3. Open the JazzAuthServer_install_dir/wlp/usr/servers/jazzop/appConfig.xml file in an editor.
    4. Locate the SAML xml section between the <!-- SAML> and <!-- end of SAML> comments. Uncomment the <samlWebSso2.0> and <authFilter> elements.
      Note: The mapTouserRegistry="User" property ensures that users are recognized by the Jazz Authorization Server. You need this property only if your deployment includes ELM clients that are based on Eclipse technology. If you are using ELM web clients only, which retrieve group information directly from SAML, you do not need to use the mapToUserRegistry="User" property.
      Example: The following sample code shows the SAML section of an appConfig.xml file that is edited to support SAML 2.0.
      <authFilter id="samlAuthFilter">
         <requestUrl id="samlRequestUrl" urlPattern="/authorize" matchType="contains" />
         <userAgent id="samlUserAgent" agent="Mozilla|Opera" matchType="contains" />
    5. Save your changes and close the file.
  2. Export the spmetadata.xml file from the Jazz Authorization Server (SAML SP) by following the instructions in step 2 of Configuring SAML web browser SSO in the Liberty profile.
    Tip: The spmetadata.xml file contains the keystore pairs that allow secure communication between the SAML IdP and the Jazz Authorization Server (SP).
    1. In a browser window, export the spmetadata.xml file by using the following URL:


      Note: The port number is defined in the appConfig.xml file.
    2. Save the file and record the location.
      Important: If you are not prompted to save the file, then there is a problem with the SAML configuration in the Jazz Authorization Server and the spmetadata.xml file is not exported. Check the SAML settings in the appConfig.xml and server.xml files.
  3. For the Jazz Authorization Server to communicate with the SAML IdP, the server must be registered as a partner in the IdP. Registering and enabling a partner depends on the SAML implementation in your IdP. Follow the SAML documentation to register and enable the partner.
  4. Export the SAML IdP metadata file so that you can add it to the Jazz Authorization Server. Follow the steps to export the metadata file for the IdP.
  5. Copy the metadata file that you exported in step 4 to the following location:


  6. Test the Jazz Authorization Server connection to the SAML IdP by using the following URL:


    Note: The port number is defined in the appConfig.xml file.

    If you configured the Jazz Authorization Server correctly, the SAML IdP login window opens.

    Note: Logging in now generates an error, which you can ignore. The purpose of this step is to ensure that the SAML login window is displayed.
  7. If your deployment includes a mix of Eclipse and web clients, you must configure the Jazz Authorization Server to support either a file-based user registry server or a Lightweight Directory Access Protocol (LDAP) server. This step provides a mechanism for Eclipse clients to authenticate.
    Remember: Web clients retrieve group information directly from the SAML IdP.
  8. Start the Jazz Authorization Server, as described in Managing users on Jazz Authorization Server.
  9. Validate the Jazz Authorization Server configuration.
    1. Open a browser window outside the Jazz Authorization Server host environment and go to the following URL:


    2. Verify that the user registry is configured correctly by going to the following URL:
