That is outdated information, in my opinion.
You should be able to control the scaling on that with sufficient machines
in your cluster; for 20,000 users, /etc/passwd (or, one would hope,
/etc/shadow) should be fine.
Now, the question is; how sure are you you're not going to greatly exceed
20,000 users?
