Description
It would be extremely useful to me if an AuthSource subclass could supply a CAPTCHA challenge image to the end user (presumably from the authenticating back-end), and subsequently get a CAPTCHA answer back.
I've been working on a ClientLogin auth source which has the drawback that sometimes Google decides to issue a CAPTCHA challenge. When this happens, there is currently no way for me to pass this on to the user, so authentication simply fails until the challenge expires.
