Update RADIUS Certificates for EAP-TTLS Devices

JumpCloud's RADIUS-as-a-Service offers Certificate-based methods for desktops, laptops, and mobile devices to verify that they are authenticating to the correct RADIUS server (so that no one else can pretend to be JumpCloud's RADIUS server). This will prevent clients from trusting RADIUS servers without the Private Key that matches this Certificate. JumpCloud strongly recommends that you leverage a certificate authentication method for this reason.

This help article explains how to update and deploy the new JumpCloud RADIUS certificate to both Windows and Mac devices.

Note:

The certificate is required for EAP-TTLS/PAP authentication methods, and for some PEAP clients as well. 

Most clients using PEAP do not need to manually add the RADIUS certificate because it is automatically acquired during the device authentication process.

Important:
  • The new certificate will be installed on JumpCloud’s RADIUS servers on July 8, 2024 and is valid until July 10, 2025.
  • To avoid a service disruption, update your certificate before July 8, 2024.

Considerations

  • If you have the current JumpCloud RADIUS certificate installed, you only need to update where it was manually installed.
  • You can install the new certificate side-by-side with the current (expired) certificate. The system will select the correct certificate.
  • To avoid service disruptions, do not remove the current (expired) certificate until it is replaced on July 8, 2024.
  • The EAP-PEAP protocol is not affected by the RADIUS certificate expiration. However, users may be prompted to grant trust to the new certificate when they connect to JumpCloud managed EAP-PEAP RADIUS servers.


Mac Setup

Note:

Make sure you have a current RADIUS certificate installed. For more information, see Configure EAP-TTLS/PAP on Mac & iOS for RADIUS.


To update the JumpCloud RADIUS certificate in macOS:

  1. Download the attached .mobileconfig file and open it in a text editor.

Note:
  • The .mobileconfig file contains the updated certificate.
  • This .mobileconfig file is not compatible with iOS/iPadOS. Users on these devices should reconnect to the RADIUS network SSID manually, which will cause a prompt for the user to download and trust the new RADIUS certificate.
  1. Add the Service Set Identifier (SSID) in between the <string> and </string> text on Line 43.
  2. Log in to the JumpCloud Admin Portal: https://console.jumpcloud.com/login.
  3. Go to Device Management > Policy Management
  4. In the All tab, click the plus icon.
  5. On the New Policy panel, select the Mac tab.
  6. Select MDM Custom Configuration Profile policy from the list, then click configure.
  1. (Optional) In the Policy Name field, enter a new name for the policy or keep the default. Policy names must be unique.
  2. In the Settings field, click upload file to upload the modified .mobileconfig file.
  3. (Optional) Select the Device Groups tab. Select one or more device groups where you want to apply this policy. For device groups with multiple OS member types, the policy is applied only to the supported OS.
  4. (Optional) Select the Devices tab. Select one or more devices where you want to apply this policy.
  5. Click Save. If prompted, click Save again.

Note:
