Intermediate Certificate Authority (CA) Installation Instructions for Plesk 10

Solution ID:    SO22410    Updated:    07/27/2016

Solution


The SSL certificates are signed by an Intermediate CA using a two-tier hierarchy, which enhances the security of the SSL Certificate.
If the proper Intermediate CA is not installed on the server, users will see browser errors and may choose not to proceed further.
 

The Intermediate CA:

  • Supplies the necessary chaining to a trusted root in an SSL connection.
  • Must be installed on the server acting as a chain link between the browser root and server certificate.

Step 1: Download the Root and Intermediate CA Certificates          

    1.   Download the root certificate.
    2.   Download the intermediate CA certificate.
 

Step 2:  Import the Root and Intermediate CA Certificates

    1.    Access the Plesk control panel
    2.    From the left hand menu, Select Domain
    3.    Select the name of the certificate from the list at the bottom of the page
    4.    Look for the dialog box on the page stating CA certificates
    5.    Paste the intermediate CA certificate first then the root certificate second.

           NOTE: The order of the certificates is critical. The intermediate certificate must be pasted first,  
           then the root certificate. DO NOT include a space between the intermediate certificate and root certificate

           Example:

           -----BEGIN CERTIFICATE-----
           [Intermediate Certificate]
           -----END CERTIFICATE-----
           -----BEGIN CERTIFICATE-----
           [Root Certificate]
           -----END CERTIFICATE-----
