I have personally loaded 10 million user accounts into FDS as a performance test (on a measly 2.4Ghz P4 machine with 512MB of RAM), and it worked just fine; not sure how many it could theoretically hold. The linux kernel has officially had support for 32-bit uidnumbers since kernel v2.4, so the maximum user id number is 4294967295, or approximately 4.3 billion. This is the same on any distribution using kernel 2.4 or newer. I am not sure about UNIX... -- mike
