I configured OpenSSL through its openssl.cnf file to copy subjectAltName from the email, e.i., subjectAltName = email:copy. Yet, when I come to sign the CSR, I see that the subject alternative name field is empty, as shown bellow:
X509v3 Subject Alternative Name:
<EMPTY>
The other thing that I noticed is that the email is not present anywhere in the certificate, although is IS present in the CSR.
How can I configure OpenSSL to copy the subjectAltName from the email?
