Wow, I'm surprised there isn't the ability to do this.  So slaves are only
really good for load balancing, not really redundancy (except manual
failover).

Hmmm.  I wonder if libnss-ldap, libpam-ldap, etc contain (or could
contain) code to fail over to a backup if the master is down.  Not quite
as efficient, since the list of backups would have to be given to every
application, but would still provide for some redundancy.

Has anyone considered adding this sort of functionality (is it even in the
protocol specs?)  Since the master knows what slaves exist, it would seem
to make sense that a client could cache a list of slaves from the master.
This sort of redundancy would seem to be a killer in a large scale
corporate environment.  Just a thought.

Cool.  Thanks!
