You always need more than two LDAP servers. In a replicated environment, two servers is never enough. If you have only two servers, you can’t easily take one off line. Three or more allows you to take one off line with much less risk of harm. If you only have two replicated servers (or partitions), taking one off-line results in only one left holding all the change, e.g., LDAP add, modify, delete, and modrn transactions. And if only one server is holding all the change, you’re out on a limb as far as recovery goes, if that server dies. The whole point of having a replicated environment is to have the ability to withstand a server failure, and in the event of one, continue service and maintain the state of the information set.
