I thought the usual ways of doing this were to either use a

validating the address.
This is the 'I have the money' way of doing this ;-)
There are at least 2 free ldap servers. Or if you are stuck with
mysql you can probably add your own field for delivery host.
The service provider I used to work for tried openldap in 98. They got
burned big time. Maybe it is up to the task today. What kind of
hardware, though, would you use for one that the OP indicates will get
a lot of writes? Everything I have read says LDAP is not for high
write problems.
1998 was a long time ago. Red Hat (fedora) directory server has claimed
good performce for several years now.

Yeah, well, I guess the Fedora Directory server is unlikely to drop its
entire datastore and will actually keep running but hey, are you going
to migrate back to ldap if you have a system that is distributed across
different mysql boxes running on cheap boxes and does its job?

what I can't figure out is why you are asking questions when you have
already decided answers...in part based on experiences from 10 years
ago.
Well, I do not work for that service provider anymore...I was just
putting forth the question they would probably ask...
In any case, the money for hardware stands I believe unless Fedora
Directory/OpenLDAP has really good performance in a heavy read/write
environment versus mysql.
