I've been using openldap's multi-master syncrepl based sync for years and it works great. But, I would like to be able to specify which IP on a multi-IP system syncrepl makes outgoing connections to other members of the sync cluster.
On my multi-IP servers I am able to get slapd to only bind to a specific IP with the appropriate -h option. That works fine. But, outgoing syncrepl connections come from the primary IP on the server.
Can anyone suggest a way to specify which IP syncrepl will use to make outgoing replication queries?
This is outside the scope pf OpenLDAP. The OS will always choose the default route for newly established outbound network connections. You would achieve your desired behavior by overriding the default route with a static route added to the routing table in the host OS. Note: this would impact all network traffic destined for a specific IP and not just syncrepl traffic.

No, that's not correct. Many applications are perfectly capable of specifying which outgoing IP to use. I just finished helping a user do it with openssh. I was expecting to find an option to tell syncrepl which outgoing IP to use. That's a fairly normal way applications accomplish this task.

I believe you're talking about https://bugs.openldap.org/show_bug.cgi?id=8847
Working contributions welcome.
