I discovered that /etc/sssd/sssd.conf contains the line:

simple_allow_users = $, initialuser

Adding other users to this line allows them to log in. This is a very
small deployment (8 users, 4 machines), so this addresses my immediate
need, but clearly isn't really the solution. I'll dig into it some more
when I have some leisure.
