Connecting to Azure Database for MySQL fails

Create an Azure Database for MySQL 5.7 instance and attempt to connect to it. The following exception is thrown:

Error: MySQL server is requesting the old and insecure pre-4.1 auth mechanism.Upgrade the user password or use the {insecureAuth: true} option.

I believe this is the same problem as mysql-net/MySqlConnector#259 with a spurious error message due to Handshake.js assuming all packets starting with 0xFE are requesting old auth.

@dbalaouras I authored a workaround in e3e123e9af7c0829a6c1417d911572a75b4a5f95 (but it hasn’t been merged in yet). I suppose you might be able to cherry-pick that fix to a local copy of the code (and/or use npm link)?

The only other workaround I can think of would be a custom MySQL proxy that sits between this code and Azure Database for MySQL, and handles the authentication correctly; that would be a rather complex project though. This wouldn’t work unless it knew your original password.

Other than that, based on what I know about Azure MySQL and mysqljs, I can’t think of an easy workaround.

@bgrainger many thanks for the followup. I need to use the original version of Ghost, hence I cannot modify it’s codebase. I guess I have to wait for your patch to get pulled, or Azure to support fast path authentication…in the meanwhile I’m dropping Azure Mysql.
