Also, e) How does the load balancer knows what mirror to use and when to switch to the other?

Hi, I am trying to configure OpenLDAP in mirror mode.
From what I understood, the documentation suggests having two servers configured in mirror mode, plus a set of replicas. (As shown in the diagram at the end of the page at http://www.openldap.org/doc/admin24/replication.html#Configuring%20the%2 0different%20replication%20types)
The documentation suggests that the backend LDAP module can be used as the load balancer. Nevertheless the documentation is missing the sections on configuring this module. http://www.openldap.org/doc/admin24/backends.html#LDAP
a) I am assuming the replicas are just read-only replicas. Right? b) If a client requires to write to the directory, how are these request forwarded to the active mirror? c) Does anyone knows how to configure the LDAP backend to act as a proxy? d) Is mirror mode mature? Is it ready for production use?
Any help or pointers are appreciated.

Responsiveness etc. When one dies a load balancer, depending how it is configured will move on to the next IP configured and move back if that one dies.
When the original MM node comes up it will catch up from the current active one via Syncrepl.
