Setting Up External PDP Integration
Activating Authorization Services
To get started, go to the Keycloak Admin Console and switch on the Authorization Enabled toggle under Capability Config. Set up your client as a resource server, define the necessary authorization scopes, and choose the appropriate policy enforcement mode. If you’re using Skycloak, you can simplify this process with their pre-built authorization recipes.
For more advanced setups, make sure to configure:
- Resource Server Settings
- Authorization Scopes
- Policy Enforcement Mode
Once that’s done, you’ll need to create precise access rules to manage resource permissions effectively.
Setting Up Access Rules
Start by defining your authorization framework:
- Resource Definition: Identify resources using URIs, types, and scopes. For example, here’s a JSON snippet for defining ‘Financial Reports’:
{ "name": "Financial Reports", "uri": "/reports/*", "type": "urn:financial-docs:resources:report", "scopes": ["view", "edit", "delete"] } - Policy Configuration: Establish how policies will be evaluated, including their order, caching preferences, and fallback behavior.
- Permission Assignment: Link specific resources to policies to guide the PDP’s decision-making process.
Connecting to External PDP
To connect Keycloak to an external PDP, you’ll need to configure endpoint details and manage how responses are handled. Key elements to set up include:
| Configuration Element | Purpose | Key Settings |
|---|---|---|
| Endpoint URL | Specifies the PDP’s location | Protocol, host, port |
| Authentication | Secures communication with the PDP | API keys or certificates |
| Timeout Settings | Handles response delays | Connection and read timeouts |
| Response Format | Defines the decision format | JSON or XML structure |
Skycloak simplifies this process with built-in integration tools that allow for automated configurations while still offering room for customization.

Testing the Integration
Adding PDP to Keycloak
To confirm the connection between Keycloak and the external PDP, focus on these key checks:
- SSL/TLS Configuration: Ensure certificates are correctly installed and validated to secure communication.
- Authentication: Verify that API keys or client credentials are working as expected.
- Network Connectivity: Confirm that Keycloak can successfully reach the PDP endpoint.
For detailed insights, check Keycloak’s server.log file. To enable more detailed logging for the PDP module, add the following to your configuration:
logger.level=DEBUG
logger.com.keycloak.authorization.pdp=DEBUG
These steps help confirm that Keycloak is securely communicating with the external PDP.
Checking PDP Responses
Once the connection is verified, test the PDP’s ability to return the correct authorization decisions. Use Keycloak’s built-in testing dashboard to simulate various access scenarios. Include a mix of common and edge cases to ensure the policies are being enforced as intended.
Troubleshooting Guide
If you encounter issues during integration, try these steps:
- Review Server Logs
Look for common errors in Keycloak’s logs, such as:- Invalid API credentials
- Incorrect endpoint URLs
- Problems with SSL certificates
- Monitor PDP Communication
Enable detailed logging to identify:- Connection timeouts
- Improper response formats
- Authentication errors
- Test Policy Enforcement
Use Keycloak’s testing tools to evaluate authorization flows across different user roles and permissions. This helps verify that the PDP’s decisions align with your access policies.
These diagnostics can help pinpoint and resolve integration problems efficiently.
