Hi!

I have this web-based service/directory which offers users access through a 
username/password-authentication process. I am wondering what if some of the 
usernames are compromised, and I actually don't want to change the username? 
Are there any tools able to run some kind of bruteforce-attack or something, 
against my web-authentication? Other alternatives? Do I really have to 
consider my whole system as compromised just because a username may be lost?

In addition, does anyone know of any tool that can help me audit the 
web-server regarding to passwordpolicy, passwordstrength etc.

I appreciate all relevant answers :-)

Very best

There are a couple of HTTP Basic auth bruteforce products out there,
THC's Hydra being one of my favourites.  You can find this product @
http://www.thc.org

Brutus is another product off the top of my head, but I tend to be
biased and say Hydra :)
