Description:
------------
I'm using recent 4.3.10 release with mysql 4.1 client libs.

I have a configuration of 2 servers. One is the MySQL database, another is apache 1.3 running PHP 4.3.10 through CGI/FastCGI interface.

All scripts are using "localhost" value in mysql_connect() function. Actually that connection is being NAT'ed with iptables to MySQL server.

When I do manual connect with telnet to localhost:3306 it works fine. Also if "localhost" is changed  to "127.0.0.1" or  direct IP of MySQL host ( 10.1.5.55 in this case ) it just works fine!
*But* when is "localhost" in mysql_connect() it simply does NOT work!

Reproduce code:
---------------
I keep getting this: 
Access denied for user: 'username@10.1.5.89' (Using password: NO)


keep in mind that I *am* providing the password:
$db = mysql_connect("localhost", "$db_username", $db_password);

this is my /etc/hosts file:
127.0.0.1	localhost localhost.localdomain

BTW, I've tried all the combinations:
127.0.0.1	localhost
or:
127.0.0.1	localhost.localdomain

RTFM: http://www.php.net/mysql_connect

"Note:  Whenever you specify "localhost" or "localhost:port" as server, the MySQL client library will override this and try to connect to a local socket..."

Read the rest from the manual page..

but can it be fixed by some workaround. I need it really bad, because there's hundreds of scripts with "localhost" in it and it couldn't be easy to change all of them to "127.0.0.1" or whatever else.

10x in advance

maybe to disable unix domain socket in mysql client?
