Can't connect to MySQL using SSL

Hello List.

I've the same problem described in http://forums.mysql.com/read.php?37,169713,169713#msg-169713

Indeed, I've a running MySQL Server on Windows with SSL support (i.e. HAVE_OPENSSL = YES).
I can connect with a ssl user using my certificates:

mysql --defaults-file="C:\Programmi\MySQL\mysql-5.1.20-beta-win32\my-small-ssl.ini" -P 5120 -ussl -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 39
Server version: 5.1.20-beta-community-nt-debug-log MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Also, I can connect using the API:

mysql_ssl_set
mysql_real_connect

The problem is when I try to connect using MyODBC 3.51.19 with the same parameters used with API and command line connections.

If I use the MyODBC GUI setup dialog:

SSL KEY:                                  C:\OpenSSL\client-key.pem
SSL CERTIFICATE:                    C:\OpenSSL\client-cert.pem
SSL CERTIFICATE AUTHORITY: C:\OpenSSL\ca-cert.pem
SSL CA PATH:                          C:\OpenSSL\
SSL CIPHER:                            DHE-RSA-AES256-SHA

the ODBC Manager gives me the following error:

Request returned with SQL_ERROR

Also, if I try to connect with ADO:

ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" _
                 & "SERVER=localhost;" _
                 & "DATABASE=database1;" _
                 & "UID=ssl;" _
                 & "PWD=;" _
                 & "SSLCA=C:\OpenSSL\ca-cert.pem;" _
                 & "SSLCAPATH=C:\OpenSSL;" _
                 & "SSLCERT=C:\OpenSSL\client-cert.pem;" _
                 & "SSLCIPHER=DHE-RSA-AES256-SHA;" _
                 & "SSLKEY=C:\OpenSSL\client-key.pem;" _
                 & "PORT=5120;" _
                 & "OPTION=" & 2 + 3 + 8 + 32 + 2048 + 16384


a "SSL Connection Error" is returned.

Venu, Jim,
your help is much appreciated.

Thank you, Santo Leto.
