Re: Error connecting through SSH Tunnel

[Georgi Kodinov]

Thanks for the SHOW CREATE USER.
Ok, so it's native authentication. All good so far.

says:

Whether client connections to the server are required to use some form of secure transport. When this variable is enabled, the server permits only TCP/IP connections that use SSL, or connections that use a socket file (on Unix) or shared memory (on Windows). The server rejects nonsecure connection attempts, which fail with an ER_SECURE_TRANSPORT_REQUIRED error.

This doesn't include a TCP connection over an SSH tunnel. Mostly because the server can't detect that.
