<br>
Today to authentication against PAM with just simple username/password I<br>
implemented UserFederationProvider and added the proper PAM login to<br>
validCredentials[1]. This covers the most basic scenario.<br>
<br>
Now I would like to cover a more complex scenario like OTP and change<br>
the flow a little bit like this:<br>
<br>
1. User providers her username<br>
2. The next screen asks to provide how many factor our user has(For<br>
example: OTP, password). We just don't know, PAM will tell what's next.<br>
3. We authenticate against it<br>
<br>
To see in practice against FreeIPA server, I just recorded it<br>
for a practical example[2].<br>
<br>
What would be the best approach to implement this flow? I was considering to<br>
move my authentication logic out of SSSD federation provider and create a PAM<br>
authenticator.<br>
<br>
Does it make sense?<br>
