When signing a request, EasyRSA ALWAYS defaults to the CA defined
Distinguished Name field order, as defined by openssl-easyrsa.cnf
configuration file.
In the unlikely event that a CSR is received with a different DN-
field order, that order can be preserved for the signed certificate.
Command 'sign-req', now has a command option 'preserve' for this.
Additional:
Use of 'preserve = yes' in openssl-easyrsa.cnf has no effect for
EasyRSA.
Testing OpenSSL directly indicates that this option may have no effect
when used in OpenSSL default configuration file openssl.cnf
Also, OpenSSL documentation for command 'ca', option '-preserveDN'
does NOT infer that this option can be used in the configuration file.
None of which is important to EasyRSA because only foreign CSRs can
have a different DN-field order, so default behavior can remain.
