"who" is based on what's in /var/log/utmp or /var/log/wtmp. If one of
those files is not present, who can't report on users. However,
/var/log/wtmp is MANDATORY on Linux and is created by init if it does
not exist.
Now, have you tried "who" as the root user? You should see AT LEAST
your login. If you see nothing if you run "who" as a normal user,
then /var/log/wtmp is not set world-readable. If you wish to allow
normal users to run "who", then do this as the root user:
# chmod ugo+r /var/log/wtmp
and it should work.
