Doc Text:	Cancelling shutdown from a GUI session now switches to running session Previously, the policykit credentials for shutting down the system were not obtained up front before logging out. Consequently, if the users cancelled the policykit authentication dialog, they were sent back to the login screen instead of the graphical user interface (GUI) session. With this update, the dialog for obtaining credentials appears up front before the logout starts. As a result, when the users cancel the authentication dialog, they are sent back to their session instead of the login screen.	Story Points:	---

Description Joe Wright 2016-03-22 16:24:53 UTC

Description of problem:
user is logged out of gui after switching from a root gui session after trying to shutdown and cancelling the shutdown

Version-Release number of selected component (if applicable):
RHEL 6.7

How reproducible:
Verified in house on a 6.6 system

Steps to Reproduce:
- Have root log into the gnome desktop
- Switch to another user without elevated privileges
- Attempt to shutdown from the menu
- The user will be prompted for the root password
- Click cancel and the user will be logged out and immediately be switch to the root desktop   <<<<<< (The problem is here) ( I believe that I should have to authenticate to return to root's desktop session)



Actual results:
- user is logged out and switched back to the root session without authentication prompt

Expected results:
- I expect that the correct behavior is for the user to be put back on his/her own desktop and not root

Additional info:
Spoke with Ray Strode about this directly, he verified it is an issue

Comment 2 Ray Strode [halfline] 2016-03-22 16:32:57 UTC

To be clear, we don't lock the screen for the root user in RHEL 6 (or earlier RHELs).  That's one of the reasons we post a warning dialog when a user logs in as root.

The bug here is that we log the user out when they shutdown, before we ask for the polkit password.  If they cancel the polkit password, we've already logged the user out so we can't perform the cancel.

We should get the polkit credentials first before doing the logout.

I don't think we should change the behavior of root locking in rhel 6 at this point. That behavior has existed since before RHEL 2.1.  See

https://wiki.gnome.org/Projects/GnomeScreensaver/FrequentlyAskedQuestions#Why_doesn.27t_my_screen_lock_when_I.27m_logged_in_as_root.3F

We did fix it for rhel 7, though.
