Kerberos RDP from Linux

Hi,

I'm trying to connect to a domain with NTLMv2 disabled via Kerberos authentication on an Ubuntu 22.04

It works fine via rdesktop directly on the machine, as well as a xfreerdp with compiled kerberos Support that I have on the this system. E.g. Remmina works fine with this setup.

When trying to log on with RDM it fails. Terminal gives the following errors:

[13:46:00:919] [26213:26228] [INFO][Devolutions.Rdp.Credentials] - parsing "X*********", "X*****.X**.X**" (Mstsc) => "Username: "X*********" Domain: "X*****.X**.X**""

I tried different ways of entering the username and domain, but wasn't successful. I tried the different Authentication method settings, including Default and Kerberos without luck.

Is there a way of specifying the path to freerdp and passing an environmental variable? That way I could make sure it uses my working freerdp with the matching kerberos Ticket?
