This is just a silly project I've been messing with the last few days to prepare for some other "just-for-fun" projects I have coming up. Rather than have to write backends for the passwd, group, and shadow databases, now I can just throw up a quick HTTP server and write the backend in any language I want, rather than just C.
It's been years since I've messed with C so I know this code is sloppy, though I'd love any feedback.
