Resolution

It has to use Version 3 certificates for CA.

Explanation is here:

OFTP2 uses: X.509
https://tools.ietf.org/html/rfc5024
//

The security features in ODETTE-FTP 2 are centred around the use of
[X.509] certificates.

X.509 Public Key Infrastructure Certificate and
Certificate Revocation List (CRL) Profile", RFC 3280,
April 2002.

This memo profiles the X.509 v3 certificate and X.509 v2 Certificate
Revocation List (CRL) for use in the Internet.

X.509 public key certificates use a signature by a trusted
certification authority to bind a given public key to a given digital
identity. This document specifies how to use X.509 version 3 public
key certificates in public key algorithms in the Secure Shell
protocol.
