Just for information, it's relatively trivial to read the
change log from LDAP and, when a change that is of interest
to you occurs, to query LDAP for the relevant data and send
it to a non-LDAP-aware program.
One of my folks did so as a perl script for a single LDAP
server in an afternoon. Making it high-availability with
multiple LDAPs took a bit longer (:-))
