基於被M$ 挑機話玩 ADFS 要用 On-Premises MFA 先夠好。 (往後就係問 M$點解 Cloud MFA 做唔到Intranet IP by pass MFA)
用最簡單嘅方法係 MFA server 安係 ADFS 同一部幾。 安裝同大部分configure 以下面URL為好, 比Microsoft Official Article 更方便

但係,要提及 MFA User Portal會無神神黐線 login 唔到, 甚至影響到一般用嘅ADFS 爛page。係安裝途中Reboot Server多的事…….
最後最經典嘅係Microsoft 嘅 article 錯誤勁多。 PowerShell Commmand 自己砌但係用黎包Parameter 嘅 Symbol 要估。。

Register ADFS Adapter落MFA Server 嘅information missing。 完全係因為好運先係另一個WordPress 到睇到。
Between <WebServiceSdkUrl> and </WebServiceSdkUrl>, enter the address for the Web Service SDK on (one of) your Multi-Factor Authentication Server installation(s). By default, this address is https://<FQDN>/MultiFactorAuthWebServiceSDK (/pfwssdk.asmx) <- 夠膽死無左條尾完全無提。Result就係浪費一日去搵點解!@#$%^&*()_
最後。 Problem Solve!
