Can't connect to MySQL

[2005]

Just got a new server. Created a db, created an user with permissions for this DB (using webmin).

My script:

define('C_HOST','localhost');
define('C_USER','dbuser');
define('C_PASS','mypassword');
define('C_BASE','mydb');

@mysql_connect(C_HOST, C_USER, C_PASS) or die(mysql_error());

Output:

Access denied for user 'root'@'localhost' (using password: NO)

Why my script is trying to connect as root if C_USER is "dbuser". Even if I change C_USER to "root" and C_PASS to MySQL root password I get the same error:

Access denied for user 'root'@'localhost' (using password: NO)

PHP Version: 5.1.4
MySQL version: 5.0.22

Do not use the @ error suppression operator in this context.

Please post the entire script and all errors it produces - run it with display_errors = on and error_reporting(E_ALL).

MarkR, there are no errors at all. The same happends with to phpMyAdmin:

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

P.S. I can login to MySQL via terminal without any problems.

I changed some permissions and now script connects with correct username, but anyway I get:

Access denied for user 'dbuser'@'localhost' (using password: NO)
I don't understand where is tyhe problem which causes "using password : NO".
