On my RH 6.1 machine, running 2.3.28 and vlock 1.3-2 I get:
[[garbage_at_wr5z garbage]$ vlock
This TTY is now locked.
Use Alt-function keys to switch to other virtual consoles.
Please enter the password to unlock.
garbage's Password:
root's Password:
 *** That password is incorrect; please try again. ***

and an authentication failure in /var/log/messages
