RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

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.

I've done a build now with the changes mentioned in comment 2.
