#10 $nas_list empty

I'm trying to get user_finger.php3 to work, but the
$nas_list variable is empty. In fact, after grepping
the entire source tree of dialup_admin, I can't seem to
find how $nas_list is generated. My nas_admin.php3
works fine and displays my four nases, so I know that
the nas table exists and is working fine. I've even
populated naslist.conf, but that didn't help. Like I
said I can't even see where/how this variable is being
generated, so I can't seem to figure out where to start
looking.

I was about to give up and code custom SQL handling to
manually re-create $nas_list from within
user_finger.php3. Can anybody offer me any advice
before it comes to that? Thanks.
