Mike's hit the nail on the head as regards why you're not hearing answers here. I know about all kinds of huge deployments, but I'm not sure if that information is secret so I have to assume that it is. Because FDS and RHDS are quite new I doubt you will find many very large production deployments _yet_. There are certainly deployments on NSDS and SunDS that have millions of entries and 10's of servers. You can do your own performance evaluation relatively easily to determine scaling for your application. The LDAP performance tools originally written for the Netscape 'Directory Server Resource Kit' are handy for this. The best versions of these right now are in the Sun DS Resource Kit which you can download for free from their web site.
