I think this is a bug, but wanted to confirm here first.
I have two accounts on machine - first one was created when I built the machine and is part of sudo group.
Other account is coming from active directory, this account also has admin permissions - that is it can execute commands using sudo. This is my normal work account and I do execute sudo commands all the times from terminal.
However if I run some GUI application that needs sudo permissions - e.g. ubuntu software center application to install new software, my active directroy password does not work. It just asks me the password, but password it needs seems be that of default login and not active directory login. I have noticed same thing happening with other GUI applications that need authentication aslo.
Is there possibility that GUI sudo authentication and terminal authuntication are following different pahs? Terminal sudo authentication does work as expected if I enter my active directory password.
