I've found out, that the problem lies in the permissions of /etc/shadow, which were wrong in my system for some reason, as I explained it in #279560. So if this gets fixed (I assume in base-passwd), the permissions of kcheckpass can be set the following way:
$ sudo chgrp /usr/lib/kde4/libexec/kcheckpass $ sudo chmod 2755 /usr/lib/kde4/libexec/kcheckpass It doesn't need the SUID bit, GUID bit and the appropriate group is enough, when /etc/shadow has the right permissions (owned and readable by group 'shadow') regards, tom -- Cannot unlock the session if the session is locked by screensaver or locked from start menu, KDE 3.5.6 https://bugs.launchpad.net/bugs/92932 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
