    Description
    
    This code allows you to configure phpPgAdmion to automatically login
    to a particular server and database with a particular default password.
    
    Please ensure that you have taken other measures to secure phpPgAdmin
    because any user selecting a server will be logged in with the specified
    username and password.
    "Installation"
    
    Add this code into lib.inc.php (usually in libraries/)
    Insert it immediately after the ini_sets (approx line 75)
    Then, modify your config.inc.php file to add a password and username.
    The two keys are default_username and default_password.
    To add a default login of john and letMeIn to server 0:
       $conf['servers'][0]['default_username'] = 'john';
       $conf['servers'][0]['default_password'] = 'letMeIn';
*/

    if( isset( $_REQUEST['server'] ) ) {
        // get the server info
        $_server_info = $misc->getServerInfo($_REQUEST['server']);
        // if a default username and password are set...
        if( isset( $_server_info['default_username'] ) and
            isset( $_server_info['default_password'] )
        ) {
            // fake out a login request with the default info
            $_POST['loginServer'] = $_REQUEST['server'];
            unset( $_POST['server'] );
            $_POST['loginUsername'] =  $_server_info['default_username'];
            $pswd_field = 'loginPassword_'.md5($_POST['loginServer']);
            $_POST[$pswd_field] = $_server_info['default_password'];
        }
    }
