Package: xscreensaver
Version: 5.42+dfsg1-1
Severity: normal
Hi,
I run xscreensaver (with xfce4) on machines that use SSSD
to managed its users. There are several source of authentification
(as allowed by SSSD) but the main one (and default one) is to
authenticate against an AD (windows kind of ldap/kerberos).
The important thing is that user names (ie logins) are of the
form name@domain
When launching xscreensaver-demo, I always got the following
message (sorry, its in French):
===================
xscreensaver-demo est lancé par l'utilisateur «name@domain» sur la machine
«myhostname».
Cependant le xscreensaver gérant l'écran «:0.0»
est lancé par l'utilisateur «name» sur la machine «domain@myhostname».
Comme ce sont des utilisateurs différents, ils ne vont pas lire/écrire
le même fichier «~/.xscreensaver», donc xscreensaver-demo ne fonctionnera
pas correctement.
Vous devez soit relancer xscreensaver-demo en tant que «name», soit relancer
xscreensaver en tant que «name@domain».
Relancer le démon xscreensaver maintenant ?
Annuler / Valider
==================
[approximate translation:]
xscreensaver-demo is launched by the «name@domain» user on the «myhostname»
machine.
However, the xscreensaver managing the screen «:0.0»
is launched by the «name» user on the «domain@myhostname» machine.
As these are two different users, they won't read/write
the same «~/.xscreensaver» file, so xscreensaver-demo won't work
correctly.
You must either restart xscreensaver-demo as «name», or restart
xscreensaver as «name@domain».
Restart xscreensaver daemon now?
Cancel / Validate
==================
Using "Annuler" (ie cancel) or "Valider" (validate) leads to the
same effect: I can manipulate the demo options through xscreensaver-demo
in any cases.
I suspect the message is due to the fact that xscreensaver(-demo?)
stores the login and the machine name under the form login@machine
but fails to correctly parse such string when login contains a '@'
character, as this is the case here.
Regards,
Vincent
