It fails connection when server uses PAM

When I try to connect as a user the server expects to authenticate via the PAM Authentication Plugin, the following error is thrown

Error: Client does not support authentication protocol requested by server;
       consider upgrading MariaDB client

After reading your node-mysql2 docs, and some investigations, I finally realized there’s no support for mysql_clear_password capabilities yet. I realized you provided an authSwitchHandler configuration setting to properly react when the server asks for specific authentication methods.

Couldn’t it be useful providing mysql_clear_password the same way mysql_native_password authentication capabilities have been already provided internally? After reading the official MySQL Clear Text Authentication piece of documentation, we could easily implement it in Javascript.

I have been silently following this conversation and don’t have any strong opinions on it, but I do agree generally that it should be opt-in only. Even MySQL’s own documentation shows they also make it opt-in only for their own clients (http://dev.mysql.com/doc/refman/5.7/en/cleartext-authentication-plugin.html).

What about this: add support for cleartext auth and “old auth” but by default only allow to use them when connecting over unix socket or to localhost or over ssl
