It sounds to me like something has gone horribly wrong with your PAM 
configuration...  That's a complicated beast that's hard to 
troubleshoot without actually being able to look at the relevant 
directories and examine the contents of the files therein. 

I've used vlock, and install it on every machine I use...  IMO it's 
the best.  It should not behave the way you describe unless you've 
typed the wrong password for your own user account, or unless 
authentication on your system is broken. 

If this is a fresh install, I'd consider re-installing it... possibly 
some post-install config script broke when you did the install.  If 
it's not, then it seems very likely that some change you've made 
recently (or some update that happened) has broken the config. 

Otherwise, you're going to have to dig through your logs and PAM 
configs to figure out what might be causing that.
