Hmmm... So long as both the LDAP servers are on the same network segment, and so long as they have separate addresses for their replication channel, then I can't see why that wouldn't work. However, LDAP, by its nature has a failover capability built in. You can just list several LDAP servers in your ldap.conf and each will be tried in turn until you get an answer. Or put a comma separated list of several servers into a ldap:/// or ldaps:/// style URI. There's also a way you can use SRV records with LDAP -- that gives you weighted load distribution over a number of servers. See RFC 3088. Note that not all LDAP clients support this, and its still only an experimental service.
