Override standard user login with the admin login

Question

I remember that on Snow Leopard when a standard user log in and screen lock, an admin user could unlock that. How to do this in Lion? Cheers

I was able to resolve this by following some instructions on the internet.    It's been a while, and I sadly can't recall which was the final solution for me but I'd start with:

which is to:
/etc/pam.d
aqua:pam.d root# diff screensaver screensaver.apple
6c6
< account    sufficient       pam_group.so no_warn group=admin,wheel fail_safe
> account    required       pam_group.so no_warn group=admin,wheel fail_safe
And I believe this changed the unlock dialog box to be the old style (yep just a comment, what gives? )
cd /etc
sudo cp authorization authorization.bak
sudo nano authorization
Press Control+W and search for "unlock the screensaver"
Change the line:
<string>The owner or any administrator can unlock the screensaver.</string>
to:
<string>(Use SecurityAgent.) The owner or any administrator can unlock the screensaver.</string>
Press Control+X to save /etc/authorization and exit nano.
