What is PingFederate?

PingFederate is an enterprise-grade identity federation platform that allows organizations to exchange identity information securely across multiple domains. It serves as both an Identity Provider (IdP) and Service Provider (SP), making it one of the most flexible federation solutions available for browser-based Single Sign-On implementations.

At its core, PingFederate enables:

PingFederate supports outbound and inbound federation use cases and can operate as:

• Identity Provider (IdP)
• Service Provider (SP)
• Federation Hub
• Authorization Server (AS)
• OpenID Provider (OP)
• Relying Party (RP)
• IdP Discovery Provider

Unlike traditional authentication systems that rely on multiple passwords across applications, PingFederate allows organizations to establish trust relationships between systems, enabling users to authenticate once and gain access to multiple applications securely.

Understanding Identity Federation

Identity federation refers to the secure exchange of identity information between organizations or domains. Rather than maintaining duplicate user accounts across multiple systems, identity federation enables one trusted organization to authenticate users on behalf of another.

For example:

This model provides several benefits:

• Reduced password fatigue
• Improved user experience
• Enhanced security
• Simplified account management
• Lower operational costs
• Better compliance and auditing capabilities

Identity federation becomes particularly important when organizations expand through mergers, acquisitions, or maintain separate user repositories across business units.

---

PingFederate and Browser-Based Single Sign-On

Single Sign-On (SSO) is one of PingFederate's primary capabilities.

Browser-based SSO enables users to authenticate once and seamlessly access multiple applications across different domains without repeatedly entering credentials.

PingFederate supports several standards for SSO implementation, including:

• SAML 1.0
• SAML 1.1
• SAML 2.0
• WS-Federation
• OpenID Connect
• OAuth 2.0

A typical SSO flow looks like this:

This standards-based approach ensures interoperability between cloud providers, enterprise applications, and partner organizations.

---

Identity Provider (IdP) and Service Provider (SP)

Understanding Identity Providers and Service Providers is fundamental to working with PingFederate.

Identity Provider (IdP)

An Identity Provider authenticates users and issues identity information.

Examples include:

• Corporate Active Directory
• Enterprise Identity Systems
• Workforce Authentication Platforms

The IdP is responsible for:

• User authentication
• Identity verification
• Token generation
• Assertion creation
• User attribute delivery

Service Provider (SP)

A Service Provider consumes identity information provided by the IdP.

Examples include:

• SaaS applications
• Customer portals
• Partner systems
• Internal business applications

The SP trusts the IdP to authenticate users and grants access based on received assertions or tokens.

---

PingFederate as a Federation Hub

One of PingFederate's most powerful capabilities is functioning as a federation hub.

Organizations often work with multiple partners using different federation protocols. Supporting each integration individually increases complexity and administrative overhead.

A federation hub simplifies this challenge by acting as a central identity broker.

For example:

• Partner A uses SAML.
• Partner B uses OpenID Connect.
• Partner C uses WS-Federation.
• Internal applications use OAuth.

PingFederate bridges these protocols through a centralized architecture, reducing implementation effort and simplifying administration.

Benefits of using PingFederate as a federation hub include:

• Centralized SSO management
• Reduced integration complexity
• Protocol bridging
• Simplified partner onboarding
• Improved scalability

---

Understanding SAML in PingFederate

Security Assertion Markup Language (SAML) remains one of the most widely adopted federation standards.

SAML consists of several building blocks:

Assertions

Assertions are XML documents generated by an IdP and sent to an SP.

They typically include:

• User identifiers
• Authentication status
• User attributes
• Session information

Bindings

Bindings define how SAML messages are transported.

PingFederate supports:

• HTTP POST
• HTTP Artifact
• HTTP Redirect
• SOAP

Profiles

Profiles define how SAML specifications are implemented for specific use cases.

Examples include:

• Browser SSO
• Single Logout
• Attribute Query

Metadata

Metadata provides standardized configuration information between federation partners.

Metadata files include:

• Certificates
• Endpoints
• Protocol support
• Binding information

Authentication Context

Authentication context provides information about how users authenticated.

Examples:

• Password authentication
• Kerberos authentication
• Multi-factor authentication

Authentication context helps Service Providers make authorization decisions and meet compliance requirements.

---

SAML Browser-Based SSO

PingFederate supports multiple browser-based SSO scenarios.

SSO Browser POST

In this model:

1. User logs into the Identity Provider.
2. User requests an application.
3. IdP generates a SAML assertion.
4. Browser sends the assertion to the SP.
5. SP validates the assertion.
6. Access is granted.

POST responses are digitally signed to ensure authenticity and integrity.

---

Browser Artifact

Browser Artifact uses an artifact rather than transferring the entire assertion through the browser.

The process involves:

• Artifact generation
• Artifact transmission
• Artifact resolution via SOAP
• Assertion retrieval

This method reduces exposure of assertion data in browser traffic.

---

SP-Initiated SSO

Service Provider-initiated SSO is one of the most common implementations in enterprise environments.

The process works as follows:

PingFederate supports several SP-initiated variations, including:

• POST-POST
• Redirect-POST
• Artifact-POST
• POST-Artifact
• Redirect-Artifact
• Artifact-Artifact

Each variation uses different combinations of transport mechanisms and bindings to accommodate diverse enterprise requirements.

---

SAML 2.0 Support in PingFederate

PingFederate provides extensive support for SAML 2.0.

Major capabilities include:

• Single Sign-On
• Single Logout (SLO)
• Attribute Query
• XASP
• IdP Discovery

SAML 2.0 remains the preferred federation protocol for many enterprises due to its maturity and interoperability across cloud providers and enterprise applications.

---

Single Logout (SLO)

Single Logout allows users to terminate sessions across multiple applications simultaneously.

Without SLO:

• User logs out of Application A.
• Sessions remain active in Applications B and C.

With SLO:

This improves security and reduces risks associated with orphaned sessions.

---

OpenID Connect and OAuth 2.0

Modern application architectures increasingly rely on OAuth 2.0 and OpenID Connect.

PingFederate can function as:

• Authorization Server (AS)
• OpenID Provider (OP)
• Relying Party (RP)

OAuth 2.0

OAuth focuses on authorization.

It enables:

• Access token issuance
• Refresh token support
• Delegated authorization
• API access control

OpenID Connect

OpenID Connect extends OAuth by adding authentication capabilities.

It introduces:

• ID Tokens
• User claims
• Authentication context

Together, OAuth and OIDC form the foundation of modern API and cloud authentication strategies.

---

WS-Federation Support

PingFederate supports WS-Federation Passive Requestor Profile, enabling interoperability with Microsoft environments such as Active Directory Federation Services (ADFS).

WS-Federation provides:

• Browser-based SSO
• Single Logout
• JWT support
• SAML assertion support

The process typically involves:

1. User requests access.
2. SP generates a token request.
3. Browser redirects to IdP.
4. User authenticates.
5. IdP issues a signed token.
6. SP grants access.

This capability makes PingFederate an excellent choice for organizations integrating with Microsoft ecosystems.

---
