The Ultimate Guide to High Availability with MariaDB

how to see cipher suites allowed in Mariabd server for client.

You are viewing an old version of this question. View the current version here.

Hello, Currently, we have a tool that has an issue connecting with our Mariadb server when the below setting is on. "require_secure_transport=ON" with TLS1.2, TLS1.3

the error I would get is Exception Devart.Data.Universal.UniException: Access denied for user 'user'@'ip' (using password: YES) Client driver error: Exception Devart.Data.MySql.MySqlException: Access denied for user 'user'@'ip' (using password: YES)

my theory is the client tool is sending a cipher suite that is not supported on MariaDB, I need to check what cipher suites are MariaDB server is accepting to narrow down the issue and send it to support. Does anyone know the command to check all the cipher suits that MariaDB is accepting? I am not a DBadmin and already google but have found anything helpful. I know there is a command to show the cipher after the user is logged in but that doesn't help since I can't even be logged in.

note: when "require_secure_transport=ON" is remove i have no issue with connection.

Thank you in advance for any guidance.

I'd suggest by looking at openssl s_client -starttls mysql .....

See man openssl-s_client for the options.

The other way is to look at the application connection with wireshark and it shows the protocol negotiation of the application.
