Hello Albert, as far as i know, that is not possible. There are 2 ways to achieve this in my opinion. 1. (That's how I do it): I have a local OpenLDAP server running on my SOGo server (on 127.0.0.1). This server is a passive replica of the main LDAP server. That means, it gets all the updates, when something changes on the LDAP server in production. (I am using the syncrepl overlay of OpenLDAP for that) 2. Using a haproxy as a TCP load balancer. Depending on the criticality of your SOGo system you should have at least two load balancers (to avoid single point of failure) I guess number 1 requires less ressources. Although it is a bit of a hassle to set up the syncrepl via LDIF files. But once you get the gist of it it runs rock solid :) Hope that helps, Best regards, Alexander Mischke

It's just to prevent problem when one server is down. Regards.
