Hello,

The general concensus in the community is that running CGIs setuid root is incredibly dangerous since no program is bug free. A bug in a program with elevated privileges can be very damaging should that program get exploited.

So, I would like to create a program that allows users to login, and then do things on the server as themselves - such as access their mail spools, add and remove files from their home directories, etc. However, I don't want to run the program setuid root to accomplish this.

How can I create a CGI that allows users to login, setuid to the logged in user, without being unsafe? Pointers to existing code would also be very much appreciated if possible.
