Help me choose an Auth library

[eluser]NateL[/eluser]
I've been around here for a good bit, so I know (vaguely) what authentication libraries are out there...

But, it's been quite a few months since I've done anything with CodeIgniter - so I need some help picking the right choice for this project, as I'm not sure what is even kept up to date any more.

What works with CI 1.7.2 ?

I'm gonna need something that's a little more than a log in script. I need something that has about 4 levels of roles.

Unregistered Users
Members (they get a control panel)
Moderators (they get a control panel, but not as beefy as the Admin panel)
Administrators (their control panel oversees every possible thing on the site)

Tank Auth - I've used this before and I liked its simplicity, but it doesn't have the Roles I'm looking for.

DX Auth - Looks very promising.

BackendPro - Liking that one too.

IonAuth - does it have role based permissions?

FreakAuth

I know there's a few others out there, and this article doing a comparison on some of the authentication systems....but it's 2010 now and some of these systems are...old. The reviews are old...so I don't even really know if the auth systems have been updated since some of the reviews were published.

Have some of the authors of these libraries disappeared? Which ones are actively being worked on and updated? Which ones are left for dead?

Would appreciate some tips. Thanks!!!

edit: I was also looking at Doctrine - Anyone experimented with the User System in Doctrine? http://www.doctrine-project.org/document...ent-system
