I performed the test on the same configuration, and can confirm this issue:

On a fresh linux mint issue, Ubuntu edition, 64bits, MATE package.

x2go package installed :


ii  x2goserver                          4.0.1.6-0~712~raring1  amd64
ii  x2goserver-extensions               4.0.1.6-0~712~raring1  all
ii  x2goserver-xsession                 4.0.1.6-0~712~raring1  all

userA creates a session with a custom desktop (x-session-manager) and
connect. Then close the session window (but do not disconnect)

UserB creates a session with "connect to Local Desktop" and log in using his
own login and ssh password

UserB can connect to UserA desktop with full access.


As a workaround, ss there any x2goserver.conf parameters that could be used
to disable the Local Desktop access?
