Overview: Federating BIG-IP systems for SAML SSO (with an SSO portal)

In a federation of BIG-IP® systems, one BIG-IP system acts as a SAML Identity Provider (IdP) and other BIG-IP systems act as SAML service providers.

This configuration supports:

  • Connections that initiate at the IdP or at SAML service providers.
  • Service providers that require different types of subject, attributes, and security settings for assertions.

About local IdP service

A SAML IdP service is a type of single sign-on (SSO) authentication service in Access Policy Manager® (APM®). When you use a BIG-IP® system as a SAML identity provider (IdP), a SAML IdP service provides SSO authentication for external SAML service providers (SPs). You must bind a SAML IdP service to SAML SP connectors, each of which specifies an external SP. APM responds to authentication requests from the service providers and produces assertions for them.

About SP connectors

A SAML service provider connector (an SP connector) specifies how a BIG-IP® system, configured as a SAML Identity Provider (IdP), connects with an external service provider.

What are the available ways I can configure a SAML SP connector?

You can use one or more of these methods to configure SAML service provider (SP) connectors in Access Policy Manager®.

  • From metadata - Obtain a metadata file from the vendor and import it into Access Policy Manager. The advantage to this method is that the vendor provides the majority of all required data, including certificates. You can complete the configuration by simply typing a unique name for the SP connector, a very few additional required fields, and browsing to and importing the file. Access Policy Manager then configures the SP connector.
  • From template - Use templates that Access Policy Manager provides for some vendors; for example, Google. The advantages to this method are that:
    • Most required data is included in the template
    • Additional required data is minimal. You can obtain it and certificates from the vendor
    After you select a template and type data into a few fields, Access Policy Manager configures the SP connector.
  • Custom - Obtain information from the vendor and type the settings into the Configuration utility. To use this method, you must also obtain certificates from the vendor and import them into the BIG-IP® system. Use this method when a metadata file or a template for an SP connector is not available.

About local SP service

A SAML SP service is a type of AAA service in Access Policy Manager® (APM® ). It requests authentication from an external SAML Identity Provider (IdP) that is specified on APM in a SAML IdP connector. (You bind a SAML service provider (SP) service to one or more SAML IdP connectors.) APM requests authentication from an IdP and consumes assertions from it to allow access to resources behind APM.

About IdP connectors

An IdP connector specifies how a BIG-IP® system, configured as a SAML service provider (SP), connects with an external SAML identity provider (IdP).

About methods for configuring SAML IdP connectors in APM

You can use one or more of these methods to configure SAML identity provider (IdP) connectors in Access Policy Manager® (APM®).

  • From metadata - Obtain a metadata file from the vendor and import it into APM. The advantage to this method is that the vendor provides all required data, including the certificate. You can complete the configuration by simply typing a unique name for the identity provider, and browsing to and importing the file. APM imports the certificate to the BIG-IP® system and configures the SAML IdP connector.
  • From template - Use templates that APM provides for some vendors. The advantages to this method are that:
    • Most required data is included in the template. (Note that the certificate is not included.)
    • Additional required data is minimal and is available from the vendor.
    APM configures the SAML IdP connector. You must obtain a certificate from the vendor and import it into the BIG-IP system.
  • Custom - Research the identity provider requirements and type all settings into the Configuration utility. Use this method when a metadata file or a template for an identity provider is not available. APM configures the SAML IdP connector. You must obtain a certificate from the vendor and import it into the BIG-IP system.
  • IdP Automation - Provide files with cumulative IdP metadata on remote systems, then configure BIG-IP IdP automation to poll the files periodically and create IdP connectors and bind them to a specific service provider (SP) service.

Task summary

Task list

Setting up SAML federation for BIG-IP® systems involves three major activities:

  • First, you set up one BIG-IP system as a SAML identity provider (IdP) system
  • Next, you set up one or more BIG-IP systems as a SAML service provider (SP)
  • Last, you go back to the IdP system and set up connectivity to the SP systems

Flowchart: BIG-IP system federation configuration with SSO portal

This flowchart illustrates the process for configuring BIG-IP® systems in federation and providing an SSO portal.

Configuration flow for SAML federation of BIG-IP systems

Setting up a BIG-IP system as a SAML IdP

You log in to the BIG-IP® system that you have selected to act as the SAML Identity Provider (IdP) so that you can configure elements that are required for SAML federation.
Log on to the BIG-IP system that you have selected to act as the SAML IdP in a SAML federation of BIG-IP systems.

Creating a virtual server for a BIG-IP (as SAML IdP) system

Before you start this task, configure a client SSL profile and a server SSL profile if you are going to create an SSL virtual server.
Note: Access Policy Manager® supports using a non-SSL virtual server for the BIG-IP® system configured as a SAML Identity Provider (IdP). However, we recommend using an SSL virtual server for security reasons. The following procedures include steps that are required for configuring an SSL virtual server, such as selecting client and server SSL profiles, and setting the service port to HTTPS.
Specify a host virtual server to use as the SAML IdP.
  1. On the Main tab, click Local Traffic > Virtual Servers .
    The Virtual Server List screen opens.
  2. Click the Create button.
    The New Virtual Server screen opens.
  3. In the Name field, type a unique name for the virtual server.
  4. In the Destination Address field, type the IP address for a host virtual server.
    This field accepts an address in CIDR format (IP address/prefix). However, when you type the complete IP address for a host, you do not need to type a prefix after the address.
  5. In the Service Port field, type 443 or select HTTPS from the list.
  6. For the HTTP Profile setting, verify that the default HTTP profile, http, is selected.
  7. For the SSL Profile (Client) setting, from the Available list, select the name of the Client SSL profile you previously created and move the name to the Selected list.
  8. For the SSL Profile (Server) setting, from the Available list, select the name of the Server SSL profile you previously created and move the name to the Selected list.
  9. Click Finished.
The virtual server for the BIG-IP system configured as an IdP now appears on the Virtual Server List. The virtual server destination is available for use in one or more SAML IdP service configurations.

Configuring an artifact resolution service for BIG-IP federation with SSO portal

Before you configure the artifact resolution service (ARS), you need to have configured a virtual server. That virtual server can be the same as one that is used for an SAML Identity Provider (IdP), or you can create an additional virtual server.
Note: F5® recommends that the virtual server definition include a server SSL profile.
You configure an ARS so that a BIG-IP® system that is configured as a SAML IdP can provide SAML artifacts in place of assertions. With ARS, the BIG-IP system can receive Artifact Resolve Requests (ARRQ) from service providers, and provide Artifact Resolve Responses (ARRP) for them. You can configure one or more ARS.
Note: In a BIG-IP system federation configuration that supports an SSO portal, you must configure one IdP service for each Service Provider. However, you do not need to configure a separate ARS for each IdP service.
  1. On the Main tab, click Access > Federation > SAML Identity Provider > Artifact Resolution Services .
  2. Click Create.
    The Create New SAML Artifact Resolution Service popup screen opens, showing general settings.
  3. In the Name field, type a name for the artifact resolution service.
  4. In the Description field, type a new description.
  5. Click Service Settings.
  6. From the Virtual Server list, select the virtual server that you created previously.
    ARS listens on the IP address and port configured on the virtual server.
  7. In the Artifact Validity (Seconds) field, type the number of seconds for which the artifact remains valid. The default is 60 seconds.
    The BIG-IP® system deletes the artifact if the number of seconds exceeds the artifact validity number.
  8. For the Send Method setting, select the binding to use to send the artifact, either POST or Redirect.
  9. In the Host field, type the host name defined for the virtual server, for example ars.siterequest.com.
  10. In the Port field, type the port number defined in the virtual server. The default is 443.
  11. Click Security Settings.
  12. To require that artifact resolution messages from an SP be signed, select the Sign Artifact Resolution Request check box.
  13. To use HTTP Basic authentication for artifact resolution request messages, in the User Name field, type a name for the artifact resolution service request and in the Password field, type a password.
    These credentials must be present in all Artifact Resolve Requests sent to this ARS.
  14. Click OK.
    The popup screen closes, leaving the Artifact Resolution Services list screen open.
The Artifact Resolution Service is ready for use.

Configuring a SAML IdP service for one SP connector
