We will not be using LDAP in the traditional sense. Instead of authentication, we will be using it to perform lookups upon incoming mail. We plan on having tens of thousands of email addresses stored in LDAP, every message that comes in is verified via LDAP that it is allowed, and then it is processed by our system. We plan on caching entries (positive and negative) for 24 hours, so as long as the look up has been done in the last 24 hours and the 1M record cache isn't exhausted it will not perform a look up. This should cut down a lot of the demand. Initially we are looking at about 100k lookups an hour, as we expand the service that can go up by 50-100k at a time.
Lots of people (myself included) use LDAP for this, among other things. Fedora DS will not blink at 100K searches per hour. I have seen 50-80K ops/minute on our LDAP servers, which are HP DL145s with 2 cores and 4 Gb memory, without any performance degradation, and I've spoken with people doing far more than that on comparable hardware. At the rates you're talking about, performance will be a non-issue.
