Summary
xrdp provides a fully functional RDP server compatible with a wide range
of RDP clients, including FreeRDP and Microsoft RDP client.
Update Information:
WARNING: Please note that this update comes with a slightly different syntax of sesman.ini file, so if you edited this file by hand, you may need to look at the .rpmnew file and merge any required changes by hand. This release also creates three files in /etc/xrdp directory if they don't already exist or are empty: - rsakeys.ini - cert.pem - key.pem Also note that in Fedora, the only backend that will really work is still Xvnc for now.
