Can't connect php/4.4.1 to Mysql 5.0.16 : Client does not support authentication protocol requested by server; consider upgrading MySQL client

[juan dela cosa]

first of all i apologize for my bad english.well said that...

i'm trying to connect via php to mysql server but i get this message on browser :

Client does not support authentication protocol requested by server; consider upgrading MySQL client

the test script is
<?php
$link = mysql_connect("localhost","prueba","prueba");
if ($link) {
echo "conexion exitosa";
}
else {
echo mysql_error();
exit;
}
?>
with the function phpinfo() show me all parameters, so that indicate that is correctly setup i think so...

and the configuration is :
S.O: win Xp pro
Apache/2.0.55 (Win32)
PHP/4.4.1
Mysql 5.0.16, MysqlClient 5.0.11

i suspect that could be the apache configuration but i´m not sure, if someone know what is happening, i really aprecited... well i apologize again for my bad english thanks
