Login screen does not show up using Duo Authentication
Today I installed Duo Authentication. It makes it possible to demand two factor authentication upon Windows login. Ref.: https://duo.com/docs/rdp
It works when I'm using a secondary PC connecting to my server by rdp.
But now I can not login using my Raspberry 2, running WTware. It worked fine before installing Duo. All I get is the background of the login screen, but no fields to choose user as before. It does in fact connect to my Windows Server, because in the lower right corner, I can choose language and even reset the server (and if I try, it resets / reboots). It seems like WTware can not render the fields for user/password input, when the Windows server has Duo installed.
See attached photo. Using evaluation because I'm troubleshooting on a all new install with newest versions.
Does anybody have any ideas for me to try?
Best,
John

Re: Login screen does not show up using Duo Authentication
Imagine we have Windows computer.
Only Windows. Fresh, just installed, not joined to domain. Nothing more. No software from DUO.
Let's run mstsc.exe on this windows machine and connect to your server with Duo Authentication installed.
Will it work?
Or it will require to install something from DUO on Windows to display authentication interface?

Re: Login screen does not show up using Duo Authentication
Thx for your reply
Yes, it works from a Windows 10 machine (lets call it "client"), clean install without any 'knowledge' of Duo, domain, etc. - just on the same LAN as the Windows server (running Windows 10) I need to connect to (lets call it "server").
It cannot be that WTware just are unable to show the window, that shows up on the "client", when I try to connect to the "server". Looks like this: I don't think this, because the window shows up after entering user name and password. And I don't even get a chance to enter those.

Will do soon.

Re: Login screen does not show up using Duo Authentication
OK, this is strange.
I installed two identical virtual machines, both running Windows 11. I did this to create the video, I just mailed to you.
The second video, I wanted to record was to show how it does (not) work when using WTware on Raspberry PI. I was surpriced to see that it works!!
So, my problem is now that it works connecting from PI to the virtual W11-server - but not to my physical machine running Windows 10. And it also works from one Windows 10/11 client to my physical machine.
My conclusion must be that WTware works - my Windows 10 installation on the server, that I need to connect to from the PI, must be the problem. I'll investigate futher...
I thank you for your time.

Re: Login screen does not show up using Duo Authentication
Everything looks good in log. No errors. I have no ideas what to do from our side. If you send me another log from wtware connecting successfully to Windows 11, I can compare them. Low probability that I will find a significant difference...

Re: Login screen does not show up using Duo Authentication
OK
I just tried something else: I installed W11 and Duo (on a secondary drive) on the server (the one I'm trying to connect to). And it worked when I tried to connect from the PI!
This just confirms what I suspected earlier - that it is my old W10-installation on the server, that messes op something about Duo, when connecting to it by RDP from Rasp PI.
Thanks for all your help - no need for further investigation. I'm planning to start over, using W11.
