FreeRDP: Unable to connect with FreeRDP3 using /sec:rdp

Describe the bug Starting from FreeRDP 3 I cannot connect to a Windows Server that has only support for /sec:rdp. Also when connecting using /sec:rdp I still get a pop-up to enter credentials (for NLA I guess?) which is disabled on purpose on the Windows Server.

To Reproduce Steps to reproduce the behavior: Connect to a Windows Server that has TLS and NLA disabled. flatpak run com.freerdp.FreeRDP /v:ip_address /sec:rdp

Enter credentials in the pop-up that follows. No connection is possible.

Expected behavior I expected it to:

1. Not prompt for credentials as no NLA should be used.
2. Make a connection to the server.

When connecting using FreeRDP 2 xfreerdp /v:ip_address /sec:rdp

It just works.

Application details For FreeRDP 3 i’m using the latest flatpak version 3.3.0. For FreeRDP 2 i’m using the latest version available 2.11.5
