You can use a few different methods on top of multi-master. HAproxy server (or other load balancer). This service listens for requests on 389/636 and forwards to the current running server Multiple records in DNS. see below Split Horizon DNS. google that one
Although some would advise against it, we use DNS to take care of this. Just make multiple entries: ldap1.example.com = 10.0.0.2 ldap2.example.com = 10.0.0.3 ldap3.example.com = 10.0.0.4 ldap.example.com = 10.0.0.2 ldap.example.com = 10.0.0.3 ldap.example.com = 10.0.0.4 point users to ldap.example.com. if ldap1.example.com dies, users will alternate hitting the dead and alive servers, ending in successful login. I get alerts if the server is down so I yank it from DNS quickly. difference between this and HAproxy is that haproxy will automatically remove the bad entries, but adds another point of failure so it's a wash to me.
