Topic: PKI Identity Certificate Enrollment on FTD

This sequence describes how FTD obtains a signed identity certificate from a Certificate Authority (CA) using manual PKCS#10 / CSR enrollment.


Why This Order?

1. Select a certificate enrollment object from FTD

Why first: Before FTD can do anything, it needs to know which CA it's enrolling with and how (SCEP, manual, self-signed). A certificate enrollment object defines the CA's parameters (CA certificate, enrollment URL or method). You must select this object to establish the trust anchor before generating any request.

Common mistake: Trying to generate a CSR before defining where it's going. Without the enrollment object, FTD has no CA context to embed in the request.


2. Generate CSR from FTD

Why second: With the enrollment object selected, FTD generates a Certificate Signing Request (CSR) - a file containing FTD's public key and identity info, signed by FTD's private key. This CSR is what you send to the CA to prove ownership of the key pair.

Common mistake: Thinking you get the certificate directly here. The CSR is not a certificate - it's a request that must be approved by the CA.


3. Obtain an identity certificate from the PKI CA server

Why third: You submit the CSR to the CA (manually, via web portal, or out-of-band). The CA validates the request and issues a signed identity certificate. This step happens outside FTD - on the CA server itself.

Common mistake: Skipping to import without actually getting the signed cert from the CA. You cannot import what doesn't exist yet.


4. Import the identity certificate into FTD

Why last: Now that you have the signed certificate from the CA, you import it back into FTD to complete enrollment. FTD matches it to the pending CSR using the key pair it generated in step 2.

Common mistake: Importing the CA certificate here instead of the identity certificate, or importing before the CA has signed it.


Mental Model

FTD defines CA context → FTD generates key pair + CSR → CA signs CSR → FTD imports signed cert

This is the standard manual enrollment flow for any PKI system: configure trust, request, sign, install.
