when configuring "Loging Prefs" you can login automatically into an account, disable Restart and Shut Down buttons, show a password hint after 3 attempts to enter a password...
and you can choose the authentication scheme you want. When you click the select button it brings an open dialog box that goes directly to a folder called "Authenticators" which only has "Kerberos.bundle" (the path to that folder is "HD/System/Library/Authenticators"). So this are great news for security concerned people. Well done Apple!!!
