This is correct, it does not exist any configuration to copy the CN to SNA
or
vice versa, although it is weird because, in fact it exists, a
configuration to
copy the SMA email address from the distinguished name. This can be
done with these settings subjectAltName=email:copy or
subjectAltName=email:move. With move I can not confirm it.

_Subject Alternative Name_

[...]
The email option include a special 'copy' value. This will automatically
include any email addresses contained in the certificate subject name in
the extension.
[...]


My solution for this was:

# export Cert_Name=www.micasa.local
# openssl req -new -keyout $Cert_Name.key -out $Cert_Name.csr -config
opensslMiCasa.cnf
# unset $Cert_Name
