Yup:
$host ldap.nodak.edu
ldap.nodak.edu is an alias for vs2.ndsu.nodak.edu.
vs2.ndsu.nodak.edu has address 134.129.111.102

There certainly can be, but in our case we have a master repository
(an Oracle database) that feeds adds/deletes/modifies directly to our
two back-end LDAP servers (bypassing the LVS-DR director).
The built-in replication has really matured. Once OpenLDAP 2.4 is out,
I need to revisit what's possible with it.
