I've selected System Preferences -> Users & Groups -> Display login window as: Name and password, but when my iMac boots, the login window displays both of the accounts I have created as being selectable. One account is an admin account, the other is not. Is this a known issue? I would like to require both a name and password anytime the user has to login (from a cold or warm boot, or upon logging out). This seems to work properly when I log out of an account. Thanks.
