xrdp and KDE Plasma desktop

[Petric Frank <pfrank@gmx.de>]

Hello,

i'm not sure where to look for this problem. Entering here because the Debian
Bookworm is used.

Installed Debian with Plasma desktop. The installed xrdp anf tigervnc-
standalone-server to allow RDP connections.

If i connect to this machine using xfreerdp the desktop is correctly shown.
But immediately a password request popup window is displayed containing this
(freely translated from german):

------------- cut ----------------
Title: Authentication required
Action: Allow control of network connections
Identity: org.freedesktop.NetworkManager.network-control
...
------------- cut ----------------

If i look at the nmcli general permissions for the id i get:

  org.freedesktop.NetworkManager.network-control              auth

If i log in locally i get:

  org.freedesktop.NetworkManager.network-control              yes


It seems that something goes wrong - but what and how to fix it ?
I use the same userid both times.

kind regards
  Petric
