Reconnect to the Same Session

Since Ubuntu 14.10, a new xrdp package has been made available in the Ubuntu repository. This package fixes a long time issue related to the fact that users could not reconnect to the same session.  If you are using the package xrdp 0.6.1-1, you do not need to perform any customization, you will reconnect automatically to the same session.
