Importing intermediate CAs

An intermediate CA store is for the intermediate CA certificates that back-end servers would normally use to complete the chain of server certificates, if any. HTTPS transactions use intermediate CAs when the server certificate is signed by an intermediate certificate authority (CA) rather than a root CA.

In FortiADC, a root CA can be imported as an "intermediate CA".

Before you begin, you must:

  • Have Read-Write permission for System settings.
  • Know the URL of an SCEP server or have downloaded the certificate and key files and be able to browse to them so that you can upload them.
To import an intermediate CA:
  1. Go to System > Certificate > Manage Certificates.
  2. Click the Intermediate CA tab.
  3. Click Import to display the configuration editor.
  4. Complete the configuration as described in Intermediate CA import configuration.
  5. Click Save when done.
  6. Repeat Steps 3 through 5 to import as many intermediate CAs as needed.
