Am I doing something wrong?  auto failover with masterha_manager running seems 
to work fine... I can alos connect to each mysql host from all the involved 
databases in the cluster

I've also connected via DBI from the mha-manager box to all the mysql 
instances, with the root account using the following script:

use strict;
use DBI;
my $dbh;
##
$dbh = DBI->connect('DBI:mysql:database=mydb;host=xx.xxx.xxx.xxx', 'root', 
'passwd') || die 
$dbh->disconnect();

I think I see the problem:

main::main(/vol/mha/master_ip_online_change:122):
122:          $new_master_handler->connect( $new_master_ip, $new_master_port, 
"root",
123:            "rootpass", 1 );

Shouldn't the "rootpass" be pulled in form the config somewhere? I don't want 
to hard code this in the script, I think that might be the issue....
