Hello,
Are you able to provide some details on the setup of this? I was able to successfully configure it on the vmware connection server but I want to configure it at the UAG instead.
I have enabled the RADIUS on the UAG:
Auth Type PAP
Shared Secret: *******
Radius Server Host Name: IP of on-prem Azure MFA server
Auth Port: 1812
Added the Internal IP of the UAG to the Azure MFA Server Radius Client list and matched the Shared Secrets. When I connect to the UAG I get standard logon prompt. Username; Password; Domain list.
