Question Shadow file permissions
We use apaches for a web stuff and we configures apache to use the etc/shadow file for the suers passwords. The problem is when you use passwd to change passwords the password gets put in the shadow file but the permissions before the change was 644 but after the change the permissions got chage to 400 read only for root. We changed the permissiong back to 644 and did a passwd again and the same thing happened. Is there a way to lock permission on the shadow file? Thanks in advance.

Making the shadow file world readable is a massive security problem. No well behaved version of unix is going to have an option to support that.
