I have looked and have not found anything yet. I'd highly recommend against doing it this way. The extra complications added by setting them up and them moving them probably just isn't worth the effort vs. setting them up the way they'll be used from the beginning. Unless your LDAP repo is obscenely large, chances are you won't save much time setting them up locally, either. If I were to go further I'd say you're asking for trouble trying to keep them synched over SSH tunnels, given the low reliability you'll have on connectivity. If it were me (and it has been several times) I'd just set up the servers as usual, in the places where they'll be used, and then use something a bit more reliable (or at least fault-tolerant) as a connectivity method, such as stunnel. Then the only thing you need to do differently is set up replication on the providers to a local IP address, and otherwsie it's the same as a standard setup.
