On the “what version of Connector/C” issue, it looks like an omission in https://mariadb.com/kb/en/about-mariadb-connector-c/#mariadb-106 that prevents an answer to your question. The “Latest Releases” section at the top tells me what’s included in 10.6.16, 10.6.17, and 10.6.18. But, the 10.6 table lower on that page lists only 10.6.1-10.6.8. If someone at MariaDB can get that fixed, that would be helpful. 😊 * Chris From: Chris Ross (cross2) <cross2@cisco.com> Date: Thursday, July 25, 2024 at 10:18 To: Sergei Golubchik <serg@mariadb.org> Cc: discuss@lists.mariadb.org <discuss@lists.mariadb.org> Subject: Re: [MariaDB discuss] mariadb connector/c client not using SSL That’s possible, but given the call to mysql_optionsv(MYSQL_READ_DEFAULT_FILE) it should be. Let me confirm that with strace… Huh. Thank you. You’re right. It reads shared libs, nsswitch and misc other system data, and openssl.cnf. Never opens my.cnf. The library is part of a mariadb 10.6.14 installation on the client, and the server seems to be 10.5.21. I don’t know what version of “connector/C” is included with mariadb 10.6.14. Do those map directly? · Chris From: Sergei Golubchik <serg@mariadb.org> Date: Thursday, July 25, 2024 at 02:37 To: Chris Ross (cross2) <cross2@cisco.com> Cc: discuss@lists.mariadb.org <discuss@lists.mariadb.org> Subject: Re: [MariaDB discuss] mariadb connector/c client not using SSL Hi, Chris, It seems that your concern is not "cannot connect with SSL", but "my application doesn't read the config file". You can verify the latter with strace or, easier, by adding some invalid option to the config file and see if there'll be a failure. Also, what is connector c version and the server version? 3.3 and 10.6? Regards, Sergei Chief Architect, MariaDB Server and security@mariadb.org On Jul 24, Chris Ross (cross2) via discuss wrote:
Hey there. I am trying to get a local application which uses the mariadb client library to connect to a server with SSL.
On my client system, I have added “ssl-ca” and “ssl-verify-server-cert” to the [client] section of my my.cnf. I can see these in effect with both “mariadb --help” and with “my_print_defaults client”. And, using mariadb client itself with all of the right connection parameters (host/port/username/port/schema) it connects just fine.
However, a program of mine which uses mysql_real_connect() fails, reporting “Access denied for user ‘foo’@’ip’ (using password: YES)”. This is, I assume, because the user on the database side requires ssl, and my client is not using ssl.
I’ve added:
(void)mysql_optionsv(conn, MYSQL_READ_DEFAULT_FILE, NULL);
Into my sources before calling mysql_real_connect(). I thought that would make it pull the params from the config file, and all should be good. But, that’s clearly not enough.
Can someone help me figure out what I’m missing? Thank you.
