Unable to RDP to AAD joined device using RDM

Unable to RDP to AAD joined device using RDM

avatar

Hi all,

I have an AAD joined device that I am trying to RDP to. The device is on the LAN, so I am just connecting to it by the internal IP address.

I can use MSTSC to connect to the machine. But I'll need to first edit the Default.RDP file for mstsc to include this:
enablecredsspsupport:i:0

Then, when I RDP, it will not ask me for creds and will take me directly to the Windows logon screen (as if I'm consoled to it). From there, I can type the AAD account and login there.

If I do not use enablecredsspsupport:i:0, MSTSC will not let me login no matter what format I use. I've tried:

.\azuread\test.account@blah.co.nz
test.account@blah.co.nz
testDomain\test.account

None of them worked. I have to change that credsssp support line to get to the Windows logon screen and enter my creds in there.

Anyway, at least it works for mstsc. For RDM, I can't get this working. Looks like in the October release, you guys removed EnableCredsSSP support, as per the changelog:
"Removed the EnableCredSSPSupport option to get rid of the confusion with the NLA option"

How can I get this working in RDM?

I've also tried setting credssp to vulnerable as per guide here:

Hello,

We removed it from the UI, but its still there, hidden by the NLA option. If I disable NLA, then accept the recommendation to switch to"Warn me", then export to RDP, I get

authentication level:i:2
enablecredsspsupport:i:0
negotiate security layer:i:0

Had you played around with NLA in your tests? It seems like the proper combination of settings.

Hi Maurice,

Yes, I've tried that already. Tried a combination of enabling and disabling NLA and choosing the different warning options.

I think I've figured this out. My default RDP template has the "prompt credentials on connection" setting and so I'll get something like this:

I was typing in the creds in the screenshot above because that's how I normally do it. But if I just click OK without entering anything, it'll take me to the Windows logon screen and from there, I can type the creds as if I'm consoled to it. This ticket can be closed now.
