Failover not failing back

Hi,

i just installed Opmanager EE and 'im trying to make failover and failback work with the central server (ver 8.8.10).

I'm following these instructions:
http://www.manageengine.com/network-monitoring/help/userguide/configure_failover_support.html

When i installed the secondary server and i arrived to the ReplicateDB.bat part, beside the fact that the port was 13307 and not 13306 as in the documentation, i got an error saying the stand by server could not connect to the primary, but if i mysqled myself from the standby server to the primary like this:
mysql -uroot -P13307 -h<primary ip>
I could get in just fine.

I tried then to use mysqldump to copy the db, (which was called "centraldb" and not "opmanagerDB" as in the documentation) and got replication and failvoer machanism working.

Problem is that it take a few minutes to failover, and that it never fail back.

So i find myself with two working portals, but any modification made on the secondary does not propagate back to the primary.

Any help?
Are the instruction i'm following the correct ones?

Thank you
