Mantis doesn't work with MySQL 4.1 ????

[RIVERA]

I installed MySQL 4.1, PHP 4 and the last versión of Mantis 1.0.....

When i try to log in Mantis, say can't connect with the db mysql. Mantis works with MySQL 4.1 ????

Thanks

PHP version 4.3.11
MySQL version 4.1.12a
Mantis version 1.0.03a

Message ...

SYSTEM WARNING. mysql_connect(). Client doesn't support authentication protocol requested by server. Consider upgrading MySQL client.

The check.php page say BAD in oppening connection to database.

The parameters in file config_defaults_inc.php are correct.

$g_hostname = 'localhost';
$g_db_username = 'root';
$g_db_password = 'thepassword';
$g_database_name = 'mysql';
$g_db_type = 'mysql';

NOTE : I execute the mantis scripts with user "root" and in schema "mysql" because i try firts creating user "mantis" with pwd "mantis", schema "mantis" and all privileges and don't work.
What it's wrong ??? please need help.

There is probably more information on this on the MySQL or php site. In MySQL 4.1, the authentication (password) scheme for MySQL changed. See http://dev.mysql.com/doc/mysql/en/old-client.html .
