I've turned off buffering for the time being

Here is the access log

There was no configuration done on the test servers.  I installed the packages,  brought up the console and made sure everything was working then ran my script.  And the replication does in fact work across all machines.  The console client is the only thing throwing errors.

Here are the subs I use to create replication objects and rep agreements.


sub add_rep_agreement
{
	my ($source, $source_port, $target, $target_port,$with_ssl, $bind_pw) = @_;
	my ($ldap, $msg);

	$ldap = conn_bind($source, $source_port, $bind_pw);

	print "adding to Replication Agreement $source -> $target\n";
	$msg = $ldap->add(
		"cn=Replication to $target,cn=replica,cn=\"$config{BASE_DN}\",cn=mapping tree,cn=config",
