i psoted a message here before few days asking how to solve this problem, fortunately
i found the solution on a website, i reseted the pass and all worked.
MySQL 4.1 uses an authentication protocal 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 a 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 do one of the following:
Upgrade all client programs to use the 4.1.1 or newer client library.
Use a user account with an old password when connecting from a pre 4.1 client.
Reset the user that needs a pre-4.1 client to use an old password:
mysql> UPDATE user SET Password = OLD_PASSWORD('mypass')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;
Tell the server to use the older password hashing algorithm:
Start mysqld with --old-passwords.
Set the password for all users that has a long password. You can find these users
with:
SELECT * FROM mysql.user WHERE LEN(password) > 16;
