✓ RADIUS Proxy Configuration Complete!
Your RADIUS infrastructure is now integrated with Secret Double Octopus.
RADIUS authentications are now protected and centrally controlled by your SDO policies.
⚙ Troubleshooting Tips
- No response from RADIUS Proxy: Verify the RADIUS Agent service is running and that UDP ports 1812/1813 are open between client and proxy.
- Authentication fails immediately: Check that the shared secret matches on the RADIUS client and in the SDO configuration.
- Requests not visible in SDO logs: Confirm the agent is registered correctly and can reach SDO cloud endpoints.
- Policy-related denials: Review RADIUS policies in SDO and confirm that the user, group, and client are in scope.
