From 37ebf87fb6fc93d445139310a1c89b98f3f514de Mon Sep 17 00:00:00 2001

Subject: [PATCH 37/39] Add new option to allow overriding the detected SCEP CA
chain
The -R option was doing double-duty for the SCEP CA.
1. It was required if the SCEP URL used TLS
2. It override the CA certificate downloaded from the SCEP server
If the chains were different then validating the SCEP responses would
fail.
