Log all login failures
 

Out forums are being accessed by roughly 10 Tor exit nodes each day, and we know who it is that's doing it. (Each time I find one though, I block him from allowing access on the site via a .htaccess file)
I'm just wondering if it's possible to log all failed login attempts into a file with the username and password they tried, the time of it and what IP.

I know it's possible to do it for the admin login (which I've set up), I just want to have it so we can see what the hacker's thinking and hopefully stop him.

Bump

also on my forum i've noticed the same. 15 20 tor exit nodes try to login every day. It's possibile to know which username they try to use?

Sadly, I would also like to know if the above is possible?? Thanks.
