title: Display devise minimum password length error on sign in page
body: <p>I am using devise's validatable module and in <code>devise.rb</code> have written <strong>config.password_length = 10..128</strong> but it does not validate the password length on sign in. Need to stop the user to login if password is not between the password length specified. </p>
  
  <p>Please help on this.</p>
  
  <p>Thanks in advance.   </p>
