phpmyadmin and phppgdmin not working with remote server

Question

I have remote server pgsqldb01 where I have postgresql and mysql databases installed, and then I have websrv02, where I try to deploy phpMyAdmin and phpPgAdmin. My DB server is running openSUSE 12.2 and webserver is running CentOS 6.3

If I try to log-in using vhosted phppgadmin and phpmyadmin, both of these webapps freeze, unable to log-in to DB servers, with no error messages. I have already configured selinux to allow remote connections to DB servers

httpd_can_network_connect --> on
httpd_can_network_connect_cobbler --> off
httpd_can_network_connect_db --> on
httpd_can_network_memcache --> off
httpd_can_network_relay --> off


<VirtualHost *:80>
    ServerAdmin webmaster@stopkaconsulting.eu
    ServerName phpmyadmin.kosare.perlur.cz
    DocumentRoot /var/www/phpMyAdmin-3.5.5-all-languages/

        Options FollowSymLinks

    </Directory>

</VirtualHost>

I can connect from websrv02 to MySQL on pgsqldb01 using mysql command line client, as well as I can create a table in MySQL server using simple php script from both php-cli and php in Apache2 webserver, however phpmyadmin on http://phpmyadmin.kosare.perlur.cz/ still does not connect to database...

I have following configuration in config.inc.php

/* Servers configuration */
$i = 0;

/* Server: pgsqldb01 [1] */
$i++;
$cfg['Servers'][$i]['verbose'] = 'pgsqldb01';
$cfg['Servers'][$i]['host'] = 'pgsqldb01.kosare.perlur.cz';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['ssl'] = false;

/* End of servers configuration */

Does anyone have a clue where could be a problem?
