[X2Go-Dev] x2godesktopsharing: Full Access not available for other users?

[Milan Knížek]

Hello list!

I am a bit confused re. the discrepancy between wiki and actual
behaviour of x2godesktop sharing:

x the wiki [1] reads that 
    With the desktopsharing function of X2go you can have full-access
    the desktop from somebody else...

x when I (USER_B) connect from a remote machine with x2goclient to
"local desktop" (USER_A logged in on tty7 of x2goserver), the
USER_A's session is shown in the lists of sessions available for
sharing, however the button "Full Access" is greyed-out and cannot be
clicked. So USER_B is only allowed to view the USER_A's deskto.

x having looked at x2godesktopsharing.git/sharetray.cpp, I can see that
this is due to "bShadow->SetEnabled ( user==getCurrentUname() );" and
have verified that the following patch removes the limitation:

-        bShadow->setEnabled ( user==getCurrentUname() );
+        bShadow->setEnabled ( true );
     }
 }

Is this intentional behaviour due to the potential security issues
mentioned here [2] (anyway, the remote user _can_ recompile the
x2goagent to get rid of the limitation)?
