/etc/shadow has wrong group

[z3non]

Binary package hint: base-passwd

according to a discussion in

https://bugs.launchpad.net/ubuntu/+source/xscreensaver/+bug/279560

I report, that I and several other users had experienced problems due to a wrong group of the file /etc/shadow by default

$ ls -l /etc/shadow
-rw-r----- 1 root root 1133 2008-10-06 19:32 /etc/shadow

which commonly leads to problems with screenlocking programs. There have been discussed several workarounds with suid-bit, but not the root of the problem, the wrong group of /etc/shadow (which should be shadow, not root).

This must have been intruduced with gutsy (according to https://bugs.launchpad.net/ubuntu/+source/kde-guidance/+bug/26175), so there should be done a permission check of /etc/shadow within a package install script for gutsy, hardy and intrepid.
