Step 5b: Exporting the Certification Authority Certificates

2/9/2009

After you obtain the valid Mobile Device Manager Gateway Server certificate, you must export the root certification authority certificate and any subordinate certification authority certificates. The following procedures assume that your root certification authority is offline and inaccessible from the company network. You perform the following procedures from a subordinate certification authority by using the Certification Authority snap-in, or from a desktop or server that has access to the Certification Authority console.

You must make sure that you follow these steps:

  • Name each exported root or subordinate certificate appropriately so that you can easily find them later.
  • Securely transfer certificates to MDM Gateway Server together with the gateway certificate. You must be able to transfer text files and certificates onto and from MDM Gateway Server.

  1. Open the Certification Authority console from any domain-joined computer or server. This console must be attached to the certification authority, either root or subordinate, that you designated for MDM deployment.

  2. Right-click the name of the certification authority and then select Properties.

  3. In the CA certificates dialog box, choose the General tab, and then select the certificate for the certification authority you want to access.

  4. Choose View Certificate.

  5. In the Certificate dialog box, choose the Certification Authority tab. Select the name of the root certification authority and then choose View Certificate.

  6. In the Certificate dialog box, choose the Details tab and then choose Copy to File.

  7. The Certificate Export Wizard appears. Choose Next.

  8. On the Export File Format page, select the DER encoded binary X.509(.CER) option.

  9. Choose Next.

  10. In the File to Export box, choose the path and name for the certificate, and then choose Next.

  11. Choose Finish. The .cer file will be created in the location that you specified in the previous step.

  12. A dialog box appears to inform you that the export was successful. Choose OK to finish.

  1. Open the Certification Authority console from any domain-joined computer or server.

  2. Right-click the name of the certification authority and then select Properties.

  3. In the CA certificates dialog box, choose the General tab, and then select the certificate for the certification authority you want to access.
