The code block which generates the log error is:
if ((!SSL_CTX_load_verify_locations(s_ctx, CAfile, CApath)) ||
(!SSL_CTX_set_default_verify_paths(s_ctx))) {
/* just a warning since this is only necessary for client auth */
syslog(LOG_NOTICE,"TLS server engine: cannot load CA data");
}
If you are not using TLS client auth (x509 client certs), then you could
ignore the error. But errors in logs are annoying, so it would be nice to
fix it.
Is /etc/pki/CA/INFN-CA.pem readable by the user Cyrus runs as?
Does the following openssl command report any errors:
openssl x509 -in /etc/pki/CA/INFN-CA.pem -text
How about this command:
openssl s_client -connect <imap_server_name>:993 -CAfile /etc/pki/CA/INFN-CA.pem
