title: Open Source login systems, what is good?
body: <p>I am starting a a new web development project and I am tired of coding login systems. This is the kind of thing that must have been done dozens of times before. I really want to use someone else's code, because it is easier than rolling my own, and it will likely be better. I prefer open source for all the usual reasons, but mostly I want the ability to change it if I don't like something and bugfixes are easier than designing a whole thing.</p>
  
  <p>I just need a login system, something that manages the username/password stuff and user registration. I don't need a whole CMS.</p>
  
  <p>I am already looking at openid.net, but What open source login systems have you worked with? What other login systems have you heard of?</p>
