+# RDP Remote Access with XRDP
+
+Note: this currently only works with RHEL8.
+
+The basic configuration in Hiera is:
+
+```
+xrdp::enable: true
+```
+
+This allows by default to create new virtual desktop sessions or to connect to a local desktop session which is shared over VNC using port 5900.
+
+Some more details could be ajusted when needed:
+
+To disallow access to a shared desktop do
+```
+xrdp::shared_desktop::enable: false
+```
+
+whereas to disallow virtual desktop sessions there is
+
+```
+xrdp::virtual_desktop::enable: false
+```
+
+Also you may choose the backend for the virtual sessions, either `libxup.so` (default) or `libvnc.so`:
+
+```
+xrdp::virtual_desktop::backend: 'libvnc.so'
+```
