Red Hat Bugzilla – Bug 115684
selinux: interesting popup: "unknown user"
Last modified: 2013-07-02 18:58:58 EDT
Description of problem:
When attempting to shutdown or reboot (click the red hat, Logout,
select shutdown or reboot from popup window) it won't work. Instead a
smaller screen pops up telling me "Unknown user" and waits for the
user to click "OK" to continue. I guess this is selinux related
because it didn't happen before.
If I choose "logout" I get back to the gdm screen without any
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Attempt to shutdown or reboot from menu
Will shutdown the session and return to the gdm login screen. From
there I am able to shutdown/reboot as usual.
Should shutdown or reboot
I think this is actually a problem within userhelper which attempts to
change the context but fails for some reason. The component should
probably be changed.

I can verify this and add my own circumstances.
Just isntalled core2 test2. Workstation install. SELinux set to warning.
three partitions: / /usr /home
Added user during install.
After first install reboot and post-install process I logged in as
user i created during install.
I mucked around a bit with epiphany. I tried to load up the RHN
taskbar icon... it don't think it popped up.
I selected 'shutdown' and waited a minute or two while nothing seemed
to be happenning.
I walked away and returned to a bare desktop (no icons, no taskbar,
yes background image) with a tiny error dialog stating "Unknown User".
Clicked 'OK' and returned to graphical logon.
Same thing happens to me. Everytime I choose reboot from the gnome
exit menu this "unknown user" box appears. Reboot fails and I am put
back to the gdm login screen. Reboot from there works.
1- I have experienced this problem when executed as a non-root user
in GNOME. (KDE only presents a logout option to the user)
2- Hitting the close button returns to the login screen.
3- When logged in as root, the system shutsdown / reboots as expected.
4- This happens in enforcing mode and in permissive mode.
5- Tried to execute "init 6" from a terminal window and the response
was "must be superuser" which seems appropriate.
5- All updates are in place as of April 12

Same here as of April 27, Rawhide (the same as test3?)
I see this in FC2 after upgrade from FC1
I was still getting this problem with the latest upgrades as of this
While cleaning-up various errors found in my boot log, I came across
the following fix for a separate problem. It has resolved the
problem of getting an "Unknown User" message when logging off as a
non root user. As well, the system now shuts down correclty, instead
of sending me to the loggin window. this is what I added:
Created the missing file: /etc/sysconfig/selinux and added the value
of 'SELINUX=disabled' (without the quotes).
Hope this helps.
Fixed a least since usermode-1.74 (present in FC3) and later.
