尝试配置 Ubuntu 23.04，以便我可以使用 RDP 从 Windows 11 PC 远程登录和管理我的 Ubuntu 桌面。
当我尝试通过 RDP 从 Windows 登录时，出现身份验证错误。
我 100% 确定我输入的密码正确。我已通过直接登录来验证该帐户是否正常工作。
用户未在任何设备上登录。

我完成的其他故障排除消除了以前的错误：
$ sudo adduser xrdp ssl-cert
$ sudo systemctl stop xrdp
$ sudo systemctl start xrdp
$ sudo reboot (rebooted after last change which was to add ssl-cert to xrdp)
有谁知道如何解决身份验证失败的问题吗？我应该使用不同的方法吗？我的预期用途是通过同一 LAN 内的 Windows PC 管理 Ubuntu PC（PC 位于不同的子网中）。
