Hello, I thank you for both your answer. OpenLDAP and Haproxy are up and running at the moment. However OpenLDAP servers are configured to run only pldaps and ldapi.
We are thinking about performance test strategies and we would like to run test that bypass the proxies as well. Either we have to find a tool that supports pldap (but that's unlikely to happen) or bind to a classic LDAPS port (that would require firewall port opening). I wondered about ldapsearch as 2.4 says "pldaps scheme unknown" whereas 2.5 directly throw a "can't contact server" (therefore finding a "missing proxy header" message on the server's log). I could imagine it could. ________________________________ De : Clément OUDOT <clement.ou...@worteks.com> Envoyé : mercredi 2 juillet 2025 16:12 À : openldap-technical@openldap.org <openldap-technical@openldap.org> Objet : Re: Proxy Protocol support for ldap client [You don't often get email from clement.ou...@worteks.com.

Hello, if that helps, here is a doc on how configure HAProxy and OpenLDAP: https://ltb-project.org/documentation/haproxy_openldap_proxy_protocol.html -- Clément Oudot | Identity Solutions Manager Worteks | https://www.worteks.com
