ERROR or 1 – Log only error messages.

WARNING, WARN or 2 – Logs warnings and error messages.

X11DisplayOffset=number

The first X display number available for xrdp-sesman. This prevents xrdp-sesman from interfering with real X11 servers. If not specified, defaults to 10.

Sets the time limit (in seconds) before a disconnected session is killed. If set to 0, automatic killing is disabled.

Policy=[Default|UBD|UBI|UBC|UBDI|UBDC]

Session allocation policy. By default, a new session is created for the combination <User,BitPerPixel> when using Xrdp, and for the combination <User,BitPerPixel,DisplaySize> when using Xvnc. This behavior can be changed by setting session policy to:

UBD – session per <User,BitPerPixel,DisplaySize>
UBI – session per <User,BitPerPixel,IPAddr>
UBC – session per <User,BitPerPixel,Connection>
UBDI – session per <User,BitPerPixel,DisplaySize,IPAddr>
UBDC – session per <User,BitPerPixel,DisplaySize,Connection>

Note that the User and BitPerPixel criteria cannot be turned off. For Xvnc connections, DisplaySize is always enabled as well.
