Thank you Russ and John.
As related requirements items, I am also looking for MIT KDC
installations with (1) greater than 50,000 accounts, and (2) greater
than 100,000 accounts (user + service principals). If anyone is
running an MIT KDC this size and can share that information it would be
greatly appreciated.
