Hi Linh,

Ah, that's because we only hardcoded 8 users in etc/runguard-config.h.
You should edit that file and add extra users, then recompile runguard
and things should work.

Note that if you also rerun configure, then you should edit
etc/runguard-config.h.in instead, since the first is generated from that
file.
