Erro MySQL secure_auth

Original post: http://anothermysqldba.blogspot.com/2014/07/mysql-secureauth-error.html

Eu abordou os erros secure_auth antes, quando ele bloqueia a replicação neste post do blog . 

No entanto, eu percebi que eu iria fazer neste blog postar uma correção mais geral ao conectar via clientes MySQL. Isto é para os servidores antes do MySQL 5.6. 

Portanto, se você receber um erro secure_auth quando a conexão ao MySQL os seguintes passos devem resolver este erro.
