The problem is that current_adm() fails for lack of read access on the
users table, when it's invoked on behalf of the unprivileged user.

I think that what you really want to be using for the lookup is
SESSION_USER not CURRENT_USER.  There's no difference at the moment,
but there will be once we have setuid functions ...
