Figure 35 - Correct HP Jetdirect CA Configuration

Be sure the Root CA of your CA Hierarchy has its public key certificate configured on Jetdirect!

Here is a question for you: When Jetdirect is acting as a client and receives the server’s certificate

signed by R2, how can it know that R2’s certificate was signed by RootCA? The answer: It cannot!

Another special thing must happen: The server must send R2’s CA certificate along with its own certificate. This allows Jetdirect to “walk the chain” and verify the certificate chain is valid. Refer to Figure 36 – Walking the Chain 1
