I am using x2go to access a couple of ubuntu/gnome systems and it works great!  I do have one nagging issue though - When I am in an x2go session and I run a tool that requires admin access, like System->Administration->Users and Groups, I do not get prompted for authentication.  Since I am not able to provide admin authentication I cannot do anything with whichever tool I am running.

If I log in local on these systems I can run the same tools with no problem, the authentication prompts work fine.

I can add gksudo to the launcher as a work-around, but I am hoping there is just a setting somewhere I am missing.  Any ideas?

Thanks,
Richard
