Problem with admin - anyone can see it

[comdawg]

I noticed that if a regular visitor comes to my Coppermine site and doesn't register, if he/she knows the admin file name (which they could if they just downloaded their own CP) they can just go into Admin without logging in.  If they try to save a new config it says they can't, but I don't want them to see those options at all.  Is there a way to make it so if you just type in the path to admin.php it will force you to log in if you aren't?

When a non-admin user tries to access the config page (http://yoursite.tld/your_coppermine_folder/admin.php), all he sees is

You don't have permission to access this page.

If this is different for your site, then post a link to your coppermine-driven gallery.
