After entering the incorrect credentials it always shows "login failed" message.
Steps to Reproduce:
Go to zanata home page.
Click on login.
Enter incorrect login credentials.
Click on login
"Login failed" message shown.
There should be an different error message have to show instead of "Login failed"
e.g Login failed : please verify user-name and password. or click on forgot password.
Also after 3 attempts it should have to block that user if exits at least for an 15 min or 1 hour. with proper message like "You have exceeded the maximum attempts please try after some time"
There should be an max attempts limit.
