[xwiki-users] How to make forgot Password link working?

Hi Folks, On login page there is a link forgot username and forgot password. When i click nothing happens.Same page gets refreshed. I am not sure do we need to do any configuration to make it work? What i observed, first i clicked forgot password and then did the login. I an directly taken to reset password page. Where i click reset password, Again nothing happens? I am not sure what is the thinking behind this functianlity. If user forgets the password how he will do the login ?. Thanks.
