I have built a Custom Authentication Method for AD FS 3 on Windows Server 2012 R2 using the following link - https://docs.microsoft.com/en-us/previous-versions/adfs-windows-server-2012R2/dn783423(v=msdn.10).
We tried using the same assembly file for running the Authentication Method on Windows Server 2016. The configuration for the Authentication Provider gets completed following the same steps as for AD FS 3. Though when I try to run the AD FS IdP initiated
sign, the Authentication Method does not come into the flow. ADFS events also do not throw any error.
Please guide if anyone has any pointers or suggestion.
