[keycloak-dev] PAM Conversations - Custom login form

[Stian Thorgersen]

Adding Bill..

It would probably still be better to use user federation for verifying
credentials, but we would need some logic on how to determine what
mechanism to use for primary authentication and secondary authentication.
Bill was talking about adding some conditional flows to the authentication
maybe that's what we need.

For now I'd focus on OTP though and then move on to smartcard afterwards.
