Hi Mark,

Thought I'd give Horizon View 5.3 a spin in my home lab with Azure Multi-Factor Authentication. (Previously Phonefactor). Set up is very similar but I have found that when i tick the box to use the same username and password for RADIUS and Windows authentication I first get my SMS which works correctly but this is followed on by a "General Authentication Failure" dialog in the view client. If I click OK, it passes me through to login with my windows credentials so i think the passing of credentials is failing somewhere. If I untick the box, I get prompted twice for AD credentials as expected and this works fine.

Thinking back, if I remember, phonefactor sent a PIN to enter in the old client whereas the Microsoft one I am currently testing requires me to reply with my PIN to a text.

Have you tried using Azure MFA yet with Horizon View? Would like to hear your thoughts.

John
