how to start a replication master-master correctly

[romain]

That is :-)

But for dsync to work correctly in 2.2.15, You have to enable empty 
password for connection from your servers, this is strange ... and this 
wasn't need in previous version (at least 2.2.12)

For example, (and correct me if I'm wrong or if I can disable empty 
password), add a passdb source :

passdb {
         driver = static
         args = nopassword=y 
allow_nets=127.0.0.1/32,local,IP_OF_SERVER_A,IP_OF_SERVER_B
}
