Hello,
i found an issue with gnome-control-center: the users control would not allow to change my password.
Running the control center from the commandlline helped:
/var/cache/cracklib/cracklib_dict.pwd: No such file or directory
I discussed my observation in #debian-gnome and got the solution: cracklib-runtime was missing. Debian has to add a recommends: cracklib-runtime in the gnome-control-center but this still will not install it in siduction. So siduction users need to install the package if they want to change their password.
apt-get install cracklib-runtime
I added issue
#1644 in the siduction bugtracker.
greetings
musca
