Scenario description

For this tutorial, there's use of a PeopleSoft application using HTTP authorization headers to manage access to protected content.

Legacy applications lack modern protocols to support Microsoft Entra integration. Modernization is costly, requires planning, and introduces potential downtime risk. Instead, use an F5 BIG-IP Application Delivery Controller (ADC) to bridge the gap between legacy applications and modern ID control, with protocol transitioning.

With a BIG-IP in front of the app, you overlay the service with Microsoft Entra preauthentication and header-based SSO. This action improves the application's security posture.

Note

Gain remote access to this type of application with Microsoft Entra application proxy.
See, Remote access to on-premises applications through Microsoft Entra application proxy.

Scenario architecture

The secure hybrid access (SHA) solution for this tutorial has the following components:

  • PeopleSoft Application - BIG-IP published service secured by Microsoft Entra SHA
  • Microsoft Entra ID - Security Assertion Markup Language (SAML) identity provider (IdP) that verifies user credentials, Conditional Access, and SAML-based SSO to the BIG-IP
    • Through SSO, Microsoft Entra ID provides session attributes to the BIG-IP
  • BIG-IP - reverse-proxy and SAML service provider (SP) to the application. It delegates authentication to the SAML IdP, then performs header-based SSO to the PeopleSoft service.

For this scenario, SHA supports SP- and IdP-initiated flows. The following diagram illustrates the SP-initiated flow.

Diagram of secure hybrid access with SP initiated flow.

  1. User connects to application endpoint (BIG-IP).
  2. BIG-IP APM access policy redirects user to Microsoft Entra ID (SAML IdP).
  3. Microsoft Entra preauthenticates user and applies Conditional Access policies.
  4. User is redirected to BIG-IP (SAML SP) and SSO occurs with issued SAML token.
  5. BIG-IP injects Microsoft Entra attributes as headers in the request to the application.
  6. Application authorizes request and returns payload.

Prerequisites

BIG-IP configuration

This tutorial uses Guided Configuration 16.1 with an Easy button template.

With the Easy Button, admins don't go between Microsoft Entra ID and a BIG-IP to enable services for SHA. APM Guided Configuration wizard and Microsoft Graph handle deployment and policy management. The integration ensures applications support identity federation, SSO, and Conditional Access.

Note

Replace example strings or values in this tutorial with those in your environment.

Register the Easy Button

Tip

Steps in this article might vary slightly based on the portal you start from.

Before a client or service accesses Microsoft Graph, the Microsoft identity platform must trust it.

Learn more: Quickstart: Register an application with the Microsoft identity platform

The following instructions help you create a tenant app registration to authorize Easy Button access to Graph. With these permissions, the BIG-IP pushes the configurations to establish a trust between a SAML SP instance for published application, and Microsoft Entra ID as the SAML IdP.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

  2. Browse to Identity > Applications > App registrations > New registration.

  3. Enter an application Name.

  4. For Accounts in this organizational directory only, specify who uses the application.

  5. Select Register.

  6. Navigate to API permissions.

  7. Authorize the following Microsoft Graph Application permissions:

    • Application.ReadWrite.All
    • Application.ReadWrite.OwnedBy
    • Directory.Read.All
    • Group.Read.All
    • IdentityRiskyUser.Read.All
    • Policy.Read.All
    • Policy.ReadWrite.ApplicationConfiguration
    • Policy.ReadWrite.ConditionalAccess
    • User.Read.All

  8. Grant admin consent to your organization.

  9. Go to Certificates & Secrets.

  10. Generate a new Client Secret and note it.

  11. Go to Overview and note the Client ID and Tenant ID.

Configuration Properties

Use the Configuration Properties tab to creat new application configurations and SSO objects. The Azure Service Account Details section represents the client you registered in the Microsoft Entra tenant, as an application. Use the settings for BIG-IP OAuth client to register a SAML SP in the tenant, with SSO properties. Easy Button does this action for BIG-IP services published and enabled for SHA.

Note

Some of the following settings are global. You can reuse them to publish more applications.

  1. Enter a Configuration Name. Unique names help distinguish configurations.
  2. For Single Sign-On (SSO) & HTTP Headers, select On.
  3. Enter the Tenant ID, Client ID, and Client Secret you noted.
  4. Confirm the BIG-IP connects to the tenant.
  5. Select Next.

Service Provider

Use the Service Provider settings to define SAML SP properties for the APM instance that represents the SHA-secured application.

  1. For Host, enter the public FQDN of the secured application.
  2. For Entity ID, enter the identifier Microsoft Entra ID uses to identify the SAML SP requesting a token.

Screenshot of options and selections for Service Provider.

  1. (Optional) For Security Settings, indicate Microsoft Entra ID encrypts issued SAML assertions. This option increases assurance that content tokens aren't intercepted, nor data compromised.

  2. From the Assertion Decryption Private Key list, select Create New.

  1. For Enable Encrypted Assertion, check the box.
  2. If you enabled encryption, from the Assertion Decryption Private Key list, select your certificate. This private key is for the certificate that BIG-IP APM uses to decrypt Microsoft Entra assertions.
  3. If you enabled encryption, from the Assertion Decryption Certificate list, select your certificate. BIG-IP uploads this certificate to Microsoft Entra ID to encrypt issued SAML assertions.

Screenshot of options and selections for Security Settings.

Microsoft Entra ID

The Easy Button has templates for Oracle PeopleSoft, Oracle E-Business Suite, Oracle JD Edwards, SAP ERP and a generic SHA template.

  1. Select Oracle PeopleSoft.
  2. Select Add.

Azure Configuration

  1. Enter Display Name for the app BIG-IP creates in the tenant. The name appears on an icon in My Apps.

  2. (Optional) For Sign On URL enter the PeopleSoft application public FQDN.

  3. Next to the Signing Key and Signing Certificate, select refresh. This action locates the certificate you imported.

  4. For Signing Key Passphrase, enter the certificate password.

  5. (Optional) For Signing Option, select an option. This selection ensures BIG-IP accepts tokens and claims signed by Microsoft Entra ID.

  1. User And User Groups are dynamically queried from the Microsoft Entra tenant.
  2. Add a user or group for testing, otherwise access is denied.

Screenshot of the Add option under Users And User Groups.

User Attributes & Claims

When a user authenticates, Microsoft Entra ID issues a SAML token with default claims and attributes identifying the user. The User Attributes & Claims tab has default claims to issue for the new application. Use it to configure more claims. The Easy Button template has the employee ID claim required by PeopleSoft.

Screenshot of options and selections for User Attributes & Claims.

If needed, include other Microsoft Entra attributes. The sample PeopleSoft application requires predefined attributes.

Additional User Attributes

The Additional User Attributes tab supports distributed systems that require attributes are stored in other directories for session augmentation. Attributes from an LDAP source are injected as more SSO headers to control access based on roles, Partner IDs, and so on.

Note

This feature has no correlation to Microsoft Entra ID; it's another attribute source.

Conditional Access Policy

Conditional Access policies are enforced after Microsoft Entra preauthentication to control access based on device, application, location, and risk signals. The Available Policies view has Conditional Access policies with no user actions. The Selected Policies view has policies targeting cloud apps. You can't deselect or move these policies to the Available Policies list because they're enforced at the tenant level.

Select a policy for the application.

  1. In the Available Policies list, select a policy.
  2. Select the right arrow and move the policy to Selected Policies.

Selected policies have the Include or Exclude option checked. If both options are checked, the policy isn't enforced.

Screenshot of excluded policies under Selected Policies on the Conditional Access Policy tab.

Note

The policy list appears once, when you select the tab. Use Refresh for the wizard to query the tenant. This option appears after the application is deployed.

Virtual Server Properties

A virtual server is a BIG-IP data plane object represented by a virtual IP address. The server listens for client requests to the application. Received traffic is processed and evaluated against the virtual server APM profile. Then, traffic is directed according to policy.

  1. For Destination Address, enter the IPv4 or IPv6 address BIG-IP uses to receive client traffic. A corresponding record appears in DNS, which enables clients to resolve the published application's external URL to the IP. Use a test computer localhost DNS for testing.
  2. For Service Port, enter 443 and select HTTPS.
  3. For Enable Redirect Port, check the box.
  4. For Redirect Port, enter 80 and select HTTP. This option redirects incoming HTTP client traffic to HTTPS.
  5. For Client SSL Profile, select Use Existing.
  6. Under Common select the option you created. If testing, leave the default. Client SSL Profile enables the virtual server for HTTPS, so client connections are encrypted over TLS.

Screenshot of options and selections for Virtual Server Properties.

Pool Properties

The Application Pool tab has services behind a BIG-IP, represented as a pool with application servers.

  1. For Select a Pool, select Create New, or select one.
  2. For Load Balancing Method, select Round Robin.
  3. For Pool Servers, in IP Address/Node Name select a node, or enter an IP and port for servers hosting the PeopleSoft application.

Screenshot of IP Address/Node Name and Port options on Pool Properties.

Single sign-on & HTTP Headers

The Easy Button wizard supports Kerberos, OAuth Bearer, and HTTP authorization headers for SSO to published applications. The PeopleSoft application expects headers.

  1. For HTTP Headers, check the box.
  2. For Header Operation, select replace.
  3. For Header Name, enter PS_SSO_UID.
  4. For Header Value, enter %{session.sso.token.last.username}.

Screenshot of Header Operation, Header Name, and Header value entries under Single sign-On & HTTP Headers.

Note

APM session variables in curly brackets are case-sensitive. For instance, if you enter OrclGUID, and the attribute name is orclguid, attribute mapping fails.

Session Management

Use BIG-IP session management settings to define conditions for user sessions termination or continuation. Set limits for users and IP addresses, and corresponding user info.

Not covered in the operations guide is single log-out (SLO) functionality, which ensures IdP, BIG-IP, and user agent sessions terminate when users sign out. When the Easy Button instantiates a SAML application in the Microsoft Entra tenant, it populates the Logout URL with the APM SLO endpoint. IdP-initiated sign out from My Apps terminates BIG-IP and client sessions.

Published-application SAML federation data is imported from the tenant. This action provides the APM with the SAML sign-out endpoint for Microsoft Entra ID, which ensures SP-initiated sign out terminates client and Microsoft Entra sessions. The APM needs to know when a user signs out.

When the BIG-IP webtop portal accesses published applications, the APM processes a sign out to call the Microsoft Entra sign-out endpoint. If the BIG-IP webtop portal isn't used, the user can't instruct the APM to sign out. If the user signs out of the application, the BIG-IP is oblivious. SP-initiated sign out needs secure session termination. Add an SLO function to your application Sign out button, to redirect your client to the Microsoft Entra SAML or BIG-IP sign out endpoint. The SAML sign out endpoint URL for your tenant in App Registrations > Endpoints.

If you can't change the app, consider having the BIG-IP listen for application sign out calls, and trigger SLO. For more information, see PeopleSoft Single Logout in the following section.

Deployment

Advanced deployment

Sometimes, the Guided Configuration templates lack flexibility.

Learn more: Tutorial: Configure F5 BIG-IP Access Policy Manager for header-based SSO

Alternatively, in BIG-IP disable the Guided Configuration strict management mode. You can manually change configurations, although most configurations are automated with wizard templates.

  1. Navigate to Access > Guided Configuration.
  2. At the end of the row, select the padlock.

Screenshot of the padlock icon.

Changes with the wizard UI aren't possible, however BIG-IP objects associated with the application published instance are unlocked for management.

Note

When you reenable strict mode and deploy a configuration, settings performed outside Guided Configuration are overwritten. We recommend advanced configuration for production services.

Troubleshooting

Use BIG-IP logging to isolate issues with connectivity, SSO, policy violations, or misconfigured variable mappings.

Log verbosity

  1. Navigate to Access Policy > Overview.
  2. Select Event Logs.
  3. Select Settings.
  4. Select the row of your published application.
  5. SelectEdit.
  6. Select Access System Logs
  7. From the SSO list, select Debug.
  8. Select OK.
  9. Reproduce your issue.
  10. Inspect the logs.

When complete, revert this feature because verbose mode generates lots of data.

BIG-IP error message

If a BIG-IP error appears after Microsoft Entra preauthentication, it's possible the issue relates to Microsoft Entra ID to BIG-IP SSO.

  1. Navigate to Access > Overview.
  2. Select Access reports.
  3. Run the report for the last hour.
  4. Review the logs for clues.

Use the session's View session link to confirm the APM receives expected Microsoft Entra claims.

No BIG-IP error message

If no BIG-IP error message appears, the issue might be related to the back-end request, or BIG-IP to application SSO.

  1. Navigate to Access Policy > Overview.
  2. Select Active Sessions.
  3. Select the active session link.

Use the View Variables link to determine SSO issues, particularly if BIG-IP APM obtains incorrect attributes from session variables.
