PingFederate OAuth 2.0 Authorization Server is a component that issues access tokens to clients after authenticating them and authorizing their requests for protected resources. This setup is crucial for enabling secure access to APIs and other resources in modern applications.
What is OAuth 2.0?
OAuth 2.0 is an authorization framework that enables third-party applications to access user resources without exposing credentials. It supports various grant types, including authorization code, implicit, client credentials, and resource owner password credentials, each suited for different use cases.

How do I create an OAuth client in PingFederate?
Creating an OAuth client in PingFederate involves defining the client’s properties, including its grant types, redirect URIs, and scopes.
Step-by-Step Guide
Create a New OAuth Client
Go to Applications > OAuth Clients and click Add.Define Client Properties
Set the client ID, client secret, and grant types.Set Redirect URIs
Enter the valid redirect URIs for the client.Assign Scopes
Select the scopes that the client is allowed to request.🎯 Key Takeaways
- Create a new OAuth client in the admin console.
- Define client properties, including grant types and redirect URIs.
- Assign appropriate scopes to the client.
How do I define resource servers in PingFederate?
Defining resource servers in PingFederate involves specifying the resources that clients can access and the scopes associated with those resources.
Step-by-Step Guide
Create a New Resource Server
Go to Applications > Resource Servers and click Add.Define Resource Server Properties
Set the resource server ID and other relevant properties.Define Scopes
Create and assign scopes to the resource server.🎯 Key Takeaways
- Create a new resource server in the admin console.
- Define resource server properties and scopes.
How do I test the OAuth 2.0 configuration in PingFederate?
Testing the OAuth 2.0 configuration ensures that everything is set up correctly and that clients can obtain and use access tokens.
Using Postman
- Open Postman and create a new request.
- Set the request type to POST and enter the token endpoint URL.
- Add the following form-data:
grant_type:authorization_codecode:<authorization_code>redirect_uri:<redirect_uri>client_id:<client_id>client_secret:<client_secret>
Common Errors
- Invalid grant: Ensure the authorization code is correct and hasn’t expired.
- Unauthorized client: Verify the client ID and secret are correct.
- Redirect URI mismatch: Ensure the redirect URI matches what was registered in the client configuration.
🎯 Key Takeaways
- Test the OAuth 2.0 configuration using Postman or similar tools.
- Check for common errors like invalid grants and unauthorized clients.
Security Considerations
Security is paramount when implementing OAuth 2.0 in PingFederate. Here are some critical considerations:
Protect Client Secrets
Store client secrets securely using environment variables or secure vaults.
Use HTTPS
Ensure all communications between clients, authorization servers, and resource servers use HTTPS to protect data in transit.
Validate Tokens
Always validate access tokens on the resource server to ensure they are valid and have the required scopes.
Regular Audits
Regularly audit your OAuth 2.0 configurations to identify and address any potential vulnerabilities.
🎯 Key Takeaways
- Protect client secrets and use HTTPS.
- Validate tokens on the resource server.
- Perform regular audits of OAuth configurations.
Comparison of Grant Types
| Grant Type | Pros | Cons | Use When |
|---|---|---|---|
| Authorization Code | Secure, widely supported | More complex setup | User-facing applications |
| Implicit | Simpler setup | Less secure, token exposure risk | Single-page applications |
| Client Credentials | Simple, efficient | No user context | Service-to-service communication |
| Password | Direct user authentication | Security risks if not handled properly | Legacy systems |
