Unable to connect to Ubuntu running RDP based remote desktop

[Adam Baxter]

Initial setup: machine was headless, set up TLS using openssl, set key location using grdctl.
Windows RDP client was unable to connect - journalctl showed that the username was unable to be retreived (from dbus?).

Set password using grdctl / https://gitlab.gnome.org/-/snippets/1778#note_1515700

Plugged a monitor and keyboard in, checked Settings and the password was garbage. Reset the password, re-enabled RDP and the Windows client was still unable to connect:

ERRCONNECT_CONNECT_TRANSPORT_FAILED refers to a network error, so unrelated to g-r-d or FreeRDP.

Basically, it means the client is gone, no more network connection (e.g. unplugged network cable, wifi error, etc.).

https://serverfault.com/questions/982679/rdp-session-is-closed-when-loggin-in-locally pointed me here.

There seems to be some problem with the username/password handling when trying to run an rdp session out of the box.

I am using a brand new Ubuntu 22.04 and different rdp clients (Microsoft Desktop Mobile, Free RDP, Mocha RDP) all fail to connect.
