I can certainly understand having a directory containing a single realm
which is made up of more than a million objects. When you deploy these
directories, how is access to the directory replicated and deployed
across the network?
If I am a multi-national with offices in New York, San Francisco,
London, and Prague, are there directory servers located in all offices
or are you expecting all traffic to travel across the WAN to a central
I ask this because it significantly impacts the discussion of the KDC
load. What is important is not the number of principals in the database
but the number of clients which are going to be making requests.
