grx, si ya lo solucione, y con la funcion OLD_PASSWORD, ya que no puede hacerlo de la forma normal, osea actualizando los archivos

Buenas...
No se si lo has resuelto pero....
El ERROR que te indica que no puedes conectarte a la DB se debe a la modificacion en la cantidad de ''caracteres'' que utilizas para la password asignada al usuario...
Hay documentacion al respecto en el sitio de MySQL...
Otra opcion es descargarte el MySQL Administrator desde el sitio oficial de MySQL donde tenes una opcion de configuracion que te permite reconocer '''OLD PASSWORD'''
extraido del manual
A.2.3 Client does not support authentication protocol
MySQL 4.1 and up uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. If you upgrade the server to 4.1, attempts to connect to it with an older client may fail with the following message:
shell> mysql
Client does not support authentication protocol requested
by server; consider upgrading MySQL client
To solve this problem, you should use one of the following approaches:
Upgrade all client programs to use a 4.1.1 or newer client library.
Uhen connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password.
Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the SET PASSWORD statement and the OLD_PASSWORD() function:
mysql> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
espero te sirva
