verification hooks #24
Description
It would be nice to have some hooks into the verify workflow, to know when a user passed/failed verification. I think the basic idea would be to add a verify kwarg to IdP.authenticate, sp.utils.authenticate, and SAMLAuthenticationBackend.authenticate, then pass verify=True when authenticating a user for verification. Maybe the default implementation in SAMLAuthenticationBackend.authenticate could send a custom user_verified signal with a success parameter. Or maybe separate signals for pass/fail.
