SAP Gateway SAML 2.0 and ADFS TOTP

Hi,

We want to implement SAML 2.0 so that users can use their AD credentials to login to SAP Fiori.

We have the documentation:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjVyseHnL3JAhVCPBoKHRtNAqMQFggd…

However The AD team has concerns on this configuration as they want to introduce TOTP on the ADFS.

Is there a documentation available which talks about this type of a scenario?

Specifically without SAP Authenticator or custom app.

regards

Keo
