[ale] LDAP Server

[Jerald Sheets]

Open LDAP doesn't per-se, but with NIC bonding and Linux-HA, you can build a
very strong highly-available situation for your environment.

We have two boxes that are replication slaves with bonded nics and then
linux-HA serving a failover service address for the two.  If one goes, the
other picks up... We counted about 4 or 5 second lag for pickup.  Couple
that with nscd caching on your end hosts, and that small burp wouldn't be
seen.

We have a master LDAP server living on a different subnet in a different
data center that replicates to the above pair of hosts.  It is where we do
all our administration, and it gets synced to the replication slaves rather
quickly.

All that is free/open, and I sort of prefer it over the evaluations we did
of RH DS.

If you need any configs/setup info, just ask.  I'll share it here so
everyone can benefit.
