Pre-built login / authentication component for a php app?

Question

I know this question has been asked before, but I haven't found any answers that seem ideal.

I have a php app that needs a login system. I'm no crypto expert by any means, and I am wary of reinventing the wheel, which has doubtless been invented many times already, and very well.

I'm wondering if anyone is aware of a good authentication component which can easily be integrated into an existing script, which adheres to all best practices and which, when combined with an ssl login, will satisfy all reasonable requirements for being secure.

I would prefer a stand-alone component, as opposed to having to setup an entire framework of some sort. (The rest of the app does not use a framework, and I dislike the idea of having to use one, just for auth.)

Thanks for your help,

Why not use LDAP ?, it's standard, secured and fairly easy.
