old_passwords is a configuration variable/flag in the MySQL configuration file. It is set Off (as
SHOW GLOBAL VARIABLES statement shows). I don't have admin privileges for the database and no
possibility to change config values. But I can connect using a Linux server, so the problem seems to
be enterily related with mysqlnd Windows driver.

You write "variable" here. The error message clearly directs you to the
configuration file (which is *not* a variable).
Please check your configuration file and report back which related settings you've
got in there.

Description:
------------
Windows 7 build 7601, Apache 2.2.24 (Win32). Upgraded PHP from 5.2.* to 5.4.15, mysql_* and mysqli_*
can't connect to any databases. Then downgraded to 5.3.25, same result.
The error is always the same:
PHP Warning: mysqli::mysqli() [<a href='mysqli.mysqli'>mysqli.mysqli</a>]:
Premature end of data (mysqlnd_wireprotocol.c:553)
PHP Warning: mysqli::mysqli() [<a href='mysqli.mysqli'>mysqli.mysqli</a>]: OK
packet 1 bytes shorter than expected
PHP Warning: mysqli::mysqli() [<a href='mysqli.mysqli'>mysqli.mysqli</a>]:
(HY000/2000): mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use
an administration tool to reset your password with the command SET PASSWORD =
PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in
mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to
remove the old-passwords flag from your my.cnf file
The weird thing is that the database is actually MySQL 5.5.24, old_password variable is Off and
passwords are actually 41 byte encoded.
The database is remote, but remote connections are allowed. I even tried the same script in Linux
based server (PHP 5.4.10) and it worked.
Both mysql and mysqli extensions are correctly loaded in php.ini.
The main difference between PHP 5.2 and newer versions is that they now use mysqlnd as driver. Maybe
it is buggy in Windows?

Test script:
---------------
<?php
$mysqli = new mysqli('aaa', 'bbb', 'ccc', 'ddd');
if($mysqli->connect_error) {
die( $mysqli->connect_error );
}
echo 'connected';
?>
Expected result:
----------------
'connected'
Actual result:
--------------
Warning: mysqli::mysqli() [mysqli.mysqli]: Premature end of data (mysqlnd_wireprotocol.c:553) in ...
on line 3
Warning: mysqli::mysqli() [mysqli.mysqli]: OK packet 9 bytes shorter than expected in ... on line 3
