Unable to view Email ID in Login Failed Page

[ImamAbdullahKhan]

As per the documentation we can use custom login page when in settings CUSTOM_FAILED_RESPONSE_VIEW calls a function like AUTH_ADFS = { 'CUSTOM_FAILED_RESPONSE_VIEW' : 'app1.views.login_failed' } and the login_failed function takes 2 arguments: request, error_message and status.

Now if I want to display for which email login is failed or user is not already registered in django app, I have request arguement only that may contain the login email, but unfortunately it doesn't have any object which stores the login email, which I think should be present so that on so that it can be used to display in the login_failed page.
