I use 2 Ubuntu 22.04 desktop systems with the names alpha1 en beta1.
On system alpha1 the use of remote desktop is enabled.
On system beta1, I start, the remote-desktop-client, Remmina and try to make a connection to system alpha1 with the RDP protocol.
This connect try failed.
On system alpha1 in the log file /var/log/syslog the message lines below are written:

How can I solve this authentication failure?
