i have no practical experience, but ...
the uid and gid are 32 bit numbers, afaik. this means, that you may have
more than 4*10^9 accounts.
one of the problems may be, that the passwd file is a simple text
file, which might cause long delays, if it must be searched for the
twenty-millionth user. buts that's more theoretical, i think ...
i know, that there are special things for large networks like novell's
directory services and a password database for pam (which might be much
more effective than a text file), but i have no real idea, what these are
and what they are for. anybody with experience with large systems?
