please explain how a user should be able to change his password without a setuid passwd. write access to /etc/spwd.db and pwd.db for everybody...?
On a box that has user access, you would need more things suid. I mostly administer web servers and a lot of other servers that people have no need to really interact with. They change passwords, etc. through a web application and it has nothing to do with the actual server. On a server that you have shell access, you probably really need to add 'passwd' to the 'suid partitiion'. You may need some other things, on some of our servers, I have 'ping' as well. As I said, this gives you some control and, regardless if you do this, you should have the minimum number of s[ug]id programs to make your system functional. Start with 'su' and 'sendmail' for a server, for a workstation, you'll probably need a couple to run X properly and probably some for convenience.
