[Samba] Authentication error., The requested encryption type is not supported by the Kerberos domain controller.

[Georg Weickelt]

Hello,

After updating to Windows 24H2, I get an error message when connecting 
to remotedesktop: "Authentication error.
The requested encryption type is not supported by the Kerberos domain 
controller."

The domain controllers run with Samba 4.21.2-Ubuntu
What can be done in this situation?

Thanks,

Georg
