Description Georges Eckenschwiller 2011-12-12 08:31:40 CET
I use as display manager lxdm and Xfce as desktop.
I get regularly  a message
"Le mot de passe n'est pas valide.
Veuillez essayer à nouveau"

I see that this is the time where mgaonline is launched.
(by changing the frequency of mgaonline).

The problem exists with mageia 1 and with cauldron.

With kdm there is no problem.
But kdm is not optimal with Xfce  (too many dependencies on qt).

A user of PCLinuxOS think it's linked to consolehelper.

Something missing ?

I think it is a bad translation.

A user of PCLinuxOS thinks that the problem could be caused by consolehelper.

I wonder if the cause is not the same as for the bug 3936.
Comment 4 Mark Meyer 2012-02-08 07:56:56 CET
I tracked this down to mgaapplet (via xprop _NET_WM_PID). Basically adding the following line to your /etc/pam.d/urpmi.updates file fixes this issue:

session optional pam_ck_connector.so

Darn. After updating it still pops up several screens with 'The password...'.
Comment 6 Mark Meyer 2012-02-11 16:34:38 CET
apparently running `mkxauth -c' fixes this. For a more permanent fix try adding that line to /etc/lxdm/PostLogin and logging out and back in again.

On my system lxdm writes a corrupted .Xauthority file and the command above writes it anew. Could you verify if that is what's causing the problem by running

xauth -f ~/.Xauthority nlist $DISPLAY

The above command should list some information. However under lxdm it doesn't output a single line.

If you can confirm, I'll be looking into a fix for upstream.
Comment 7 Georges Eckenschwiller 2012-02-11 20:43:18 CET
I tested the solution with mageia1 and with cauldron.
I do not obtain any more the message of blocking.

It remains to verify if mgaapplet work correctly.
I shall see tomorrow, after an update of my local mirror of cauldron.
Comment 8 Georges Eckenschwiller 2012-02-12 11:23:01 CET
I had updates for mageia1 and for cauldron.

Mgaapplet works now correctly, in both cases.
Is it possible to patch the lxdm package, while waiting for the correction upstream?
Comment 9 Jani Välimaa 2012-02-25 12:22:31 CET
Added mkxauth to PostLogin script and pushed new release. Please test it.

This also fixed my problem where I couldn't start netcenter by clicking net_applet in system tray. Before it just said my password was wrong even I didn't enter it to anywhere.
Comment 10 Georges Eckenschwiller 2012-02-26 10:18:56 CET
By me too, everything works. I close the report.
Comment 11 Georges Eckenschwiller 2012-05-22 16:15:38 CEST
I just repeat the installation of lxdm with mageia1.
The problem is still present with mageia1
Comment 12 Georges Eckenschwiller 2012-05-24 21:19:31 CEST
I was wrong. 
I just tested and mgaapplet works correctly with Mageia1, without further corrective.
