Additional Google Apps authentication security measures

For schools that had sign up for Google Apps For Education, when you log-in at the School Portal, your login request will now be challenged by CAPTCHA from Google Apps if Google Apps suspect illegal intrusion such as after too many incorrect login attempts.  A CAPTCHA ensures that a real person is attempting to log in, and not a computer trying random strings.
We have enhanced to incorporate CAPTCHA challenge on web portal login page whenever the above failure is returned from google.  User is required to enter the username and password, and the letters from the distorted picture to UNLOCK the account.

Once the user has successfully responded to the challenge together with correct password, you will pass the login authentication.

You should not get a CAPTCHA if things are working normally.

* Note: CAPTCHA is a type of challenge-response test used in computing to determine whether or not the user is human.  A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.  Refer http://en.wikipedia.org/wiki/CAPTCHA for definition.
