Description Heiko Adams 2012-06-29 11:27:56 EDT
Description of problem:
LightDM offers the users "lightdm" and "root" for login in its userlist. But these users shouldn't be there because it should be impossible to login as these users.

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

How reproducible:

Steps to Reproduce:
1. make shure lightdm is your displaymanager
2. reboot the system
Actual results:
LightDM's userlist has entrys for "lightdm" and "root"

Expected results:
LightDM's userlist should only list "normal" users which can login

As far as I can tell, that's a bug elsewhere (accountservice?), lightdm.conf already contains:
Comment 2 Rex Dieter 2012-06-29 11:39:16 EDT
though I suppose adding those 2 to the explicit blacklist:
couldn't hurt
Comment 3 Christoph Wickert 2012-06-29 11:43:35 EDT
Last time I tested, munimum-uid was already enough. I guess Heiko is using an oudated config.

Heiko, can you make sure your config is up to date?
Comment 4 Heiko Adams 2012-06-29 11:51:35 EDT
I didn't change anything on my config so it should be up2date
Comment 5 Heiko Adams 2012-06-29 11:52:01 EDT

Comment 6 Rex Dieter 2012-06-29 11:56:20 EDT
Oh sorry, the file I meant was

which has a comment about how accountsservice is used instead,

# NOTE: If you have AccountsService installed on your system, then LightDM will
# use this instead and these settings will be ignored
Comment 7 Gregor Tätzner 2012-06-29 12:01:41 EDT
 users.conf is ignored by lightdm if accountsservice is running. For some time now user filtering is based on login shell*

@Heiko is nologin on lightdm user set in /etc/passwd?

Comment 8 Rex Dieter 2012-06-29 12:06:01 EDT
In particular, what does this say?

$ dbus-send --system --print-reply \
  --dest=org.freedesktop.Accounts /org/freedesktop/Accounts \

for me, I get :
method return sender=:1.12 -> dest=:1.129 reply_serial=2
   array [
      object path "/org/freedesktop/Accounts/User1001"
      object path "/org/freedesktop/Accounts/User1000"

$ rpm -q accountsservice
Comment 9 Heiko Adams 2012-06-29 12:09:05 EDT
$ cat /etc/passwd|grep lightdm

$ cat /etc/passwd|grep root

$ rpm -q accountsservice

What happens when you upgrade to accountsservice from updates-testing?
Comment 11 Heiko Adams 2012-06-29 12:29:15 EDT
Updating to accountsservice from updates-testing solves the problem
Comment 12 Rex Dieter 2012-06-29 12:36:16 EDT
OK, I'm conviced this is an accountsservice bug now, but looks like
got pulled

and we have a new one pending:

either fixes our particular problem here (for me, at least).
Comment 13 Gregor Tätzner 2012-07-02 02:46:53 EDT

Can you push this update also to f16? lightdm in f16 should be affected by this issue, too
Comment 14 Fedora Update System 2012-07-02 09:28:00 EDT
accountsservice-0.6.21-2.fc17 has been submitted as an update for Fedora 17.
Comment 15 Rex Dieter 2012-07-02 09:34:22 EDT
Re: comment #13

Testing on f16, I don't experience this bug with
do you?
Comment 16 Gregor Tätzner 2012-07-02 11:49:07 EDT I don't have a f16 system here. But probably you are right and the old accountsservice version is not affected by this issue.
Comment 17 Fedora Update System 2012-07-02 18:29:09 EDT
accountsservice-0.6.21-2.fc17 has been pushed to the Fedora 17 stable repository.  If problems still persist, please make note of it in this bug report.
