Mac: How to log in as different user when Mac requires password to wake from sleep?

Question

If your Mac is set up to require a password when being awoke from sleep or the screen saver is it possible to log in as a different user? If so how?

On Mac OS X Snow Leopard and previous, the Switch User button appears on the password dialog:

On Mac OS X Lion, the button appears at the bottom of the screen:

Thanks! That's what I thought but had to look a bit harder for it in Lion. It's no longer in the dialog as you've shown. It's now at the bottom of the lock screen.

Ah, so you're right. I don't have Lion so I didn't know they moved it. I added that detail to my answer, thanks!

FYI- there is a related bug in Mountain Lion if there is only one Local user account and a Network user wants to log in from the lock screen.
