How to make a fallback page for HTTP Basic Auth?

[artjoms15]

Hello!
Does anyone has a working solution for a fallback page if a user fails to authenticate through SSO.
The case is that I don' t know how to achieve that customer should enter his credentials if Apache isn' t able to find $ENV{ REMOTE_USER} Well I understand that I should make a simple form , but what data should I send and more important compare to what? Well we don' t have DB backend so it might be an interesting way to think of

Thanks in advance!
