Hi Everyone,
Thought I would share some information about Authentication to AD and using Microsoft NPS for radius auth providing MFA when connecting to the Publishers with SSH. This is useful instead of using the default shared account.
The information I obtained to get this working was obtained from the following sources, it was quite straight forwarded and implemented without much difficulty… and I am no Linux admin.
Introduction to network user authentication with SSSD | Ubuntu
How to set up SSSD with Active Directory | Ubuntu
Azure MFA for SSH using NPS/MFA Extension
Good luck with it, hope someone else finds this helpful.
