CodeIgniter Authentication System that allows 3rd party auth?

My question is rather simple. Is there a system for CodeIgniter that allows both local and 3rd party login? (Such as FB/Twitter/Google etc.)
I've tried A3M but it's hard to use and requires tinkering before it will even work out of the box, as is the case with outdated software.
My current solution is flexi auth, however it doesn't offer 3rd party login at all, and after an email to the developer it doesn't look like he's planning on integrating it anytime soon.
So does anyone know of a good system that is up-to-date and provides both 3rd party and local login?
If there isn't one, what other PHP framework does have such a package?
Edit for Clarity: I'm looking for a system that does both these things. While I appreciate the answers and comments with systems that I can integrate myself, the end result of that will be shaky at best. There's gotta be someone who's done this before, all integrated into one package so it's designed to work together.

I was also looking for something like this just a month ago, but unsuccessfully. The only framework that has it all integrated in a simple way that I have seen is meteor, but it is not a PHP framework.
I had to do it myself by wrapping different PHP libraries in CI libraries. The source code is on github: CI Twitter and Who You Meet (a live web app), that has Twitter, LinkedIn and Facebook authentication and also a lot of local authentication logic with email verification and password recovery.
I know it can be considered a shameless promotion, but I hope it is useful. Although it is not exactly what you are looking for, it seems to be rather stable, so feel free to re-use it.
Maybe you will have time to extract all this logic in a standalone library (like I did for twitter) for other folks to use :)

If you want a CI OAuth2 implementation you can use this library which is both client and server:

Otherwise for OpenID use this library:

Port Codeigniter App to PyroCMS

I'm working on a web application in Codeigniter. I'd like to integrate the functionality of my application with a CMS so that site admins can easily update the site (about pages, blog, etc). Is this easily done with PyroCMS or another Codeigniter-based CMS? Will I need to drastically restructure my existing app?

From my own experience integrating an app inside Expression Engine I can say that a CMS changes the way you usually work with CI. So be prepared to make some adjustments. Every CMS will come with it's perks and differences. It shouldn't be a big problem though.
If you want to use PyroCms take a look at this doc first:
http://www.pyrocms.com/docs/2.0/developers/creating-custom-modules
If you're looking for alternatives, there are a lot. It seems almost everyone working with CI has made it's own.
Here are a few:

http://www.halogy.com/
http://codefight.org/
http://www.getfuelcms.com/
Also make sure you check out CI Bonfire, it's not a CMS but does help you when you start up a new project with a basic admin wrapper, which is sometimes more useful than a CMS:

This was answered a year ago and answered well, but my support guy has forwarded me a few emails from users asking about this page.
When people talk about Content Management Systems they often suddenly get the idea of rigid backends where you applications have to follow specific rules. While PyroCMS certainly has a few conventions you are free to build your modules just like they are a CodeIgniter application, on the frontend or the backend.
If you want to use Models, Controllers, Views, REST API's, SOAP, whatever the hell, then you can do that.
But, we also offer some awesome tools to make building modules CRAZY-fast. Hate writing CRUD? Well don't bother. Using the Streams API you can leverage the build in "Custom Data" system we use to rock out chunks of interface for you.
Using PyroCMS for your application is certainly not "hacking it into a CMS", this is the exact use-case it was built for.
If you have an existing application, while you can't "put PyroCMS into your app" you can certainly convert your application to a module easy enough.

The simplest way of doing it is to write your models around the CMS' database. Host the CMS at a subdomain with authentication for your admins. (admin.mysite.com) or something and then use the same database to power your front-end for your site.
Is it the best approach? Probably not.
Will it work? Yes.
You will probably find it hard to expand vertically & add new features if you're relying on a 3rd party CMS for data entry & backend.

Is there an easier way to implement openid?

I've been banging my head against the wall trying to add openid to my PHP webapp, but none of the libraries provided seem to do it in a clean and simple way.
Is there any way to implement openid SSO without being forced into more design choices than is necessary?
The janrain library - being the most popular - is also the most unwieldy, although it seems to be the only one getting significant maintenance. Aside from lacking a clear and simple tutorial, it also imposes some strange filesystem requirements and code dependencies.
Any and all suggestions are welcome. I realize I'm interacting with other servers and that redirects and callbacks are required. Please bear in mind, this isn't my main complaint, I understand the nature of what I'm working with.
I just wish it was easier and more clearly laid out!

If you're using PHP5, I suggest trying LightOpenID.

I use the Zend openid library (best of a bad bunch), but it doesn't support all the latest openid features - not found a perfect implementation yet tbh..

Tutorial describes how to implement Google login( yahoo,etc only just change the URLs, source code is same) in PHP using LightOpenID.

What is the best forum plug-in solution for the Symfony framework?

I'm looking for a good solution to integrate a forum into a symfony application.
Something like phpBB would be excellent. I've seen phpBB plugins to integrate with symfony but that's not enough for my purposes, also, mapping database tables is a lame approach in my opinion.
If anybody knows a good working forum component for Symfony then I would really apreciate it. :)
Also, it needs to work with Doctrine.
Thanks!

I've found sfDoctrineSimpleForumPlugin Thanks for all the responses, hope this works :) !
The author made even some changes today after this post

If you're discounting the prestaForumConnectorPlugin which connects sfGuard and PHPBB3, then you may have to write your own connector. You should check if any resources exist on the websites of your favourite PHP forum.
One option is Invision Power Board (IPB) v3, as their developer resources explain how to integrate your own code (ie. symfony) into their system, including single sign-on: http://community.invisionpower.com/resources/official.html?category=41
I have integrated IPB v2 with symfony, and it wasn't ideal - there was no developer interface at that time to make IPB respect symfony. I had to hack around in the IPB source to make it work, but after discussing it with Invision was assured this would not be necessary with v3. This seems to now exist, which would be where I would start.
NB. IPB is not free, so hopefully this is not a sticking point for you.

I've integrated Phorum with symfony before - there's some old and semi-out of date documentation on the web for doing this, but essentially Phorum has an architecture that allows its user authentication to be easily overridden. You will then need to write a controller to wrap the forum calls too, and apply the main site templating (if you need that).

There are a couple of forums which use the Symfony frmaework. They are listed on the Symfony forum plugins page.
The most popular is the sfSimpleForum, which was built by Francois Zaninotto, one of the original Symfony developers.
There is little development in this area however, possibly because forums are the 'old' way of allowing users interact online and are gradually being replaced with new techniques.

Easiest way to implement an online order tracking database

I've been asked by a client to make an online tracking system for work we do for them (we will be typesetting a high volume of books for this client). Basically, it would be a database showing the books we are currently working on, with information on what stage of the project we are at, and estimated completion dates. The only people with access to this system would be us and employees of the client company.
I've worked in MySQL and PHP before; should I just go with what I know? This answer to a similar question suggests using Google Apps. I don't have any experience with Python, but happy to learn...

You're the only one using this therefore I see no reason to use Google Apps. I'm usually weary of people suggesting Google Apps, Amazon's s3, Microsoft Azure, etc. Also, you're going to be using a radically different data store. Unless you want an excuse to learn to do Google Apps and Python, I'd say go with MySQL+PHP and be done with it! In short, there aren't really any technical reasons for you to go with Google Apps here.

Sticking with what you know is always a good solution when dealing with delivering products to customers. No customer likes to be your guinea pig while you learn a new technology, although that's often how it's done. If you are comfortable with MySQL and PHP then stick with it if it satisfies your requirements, if it seems not to then look for libraries, frameworks and components written in PHP that might help you reach that goal. If you still have difficulties (unlikely given the scope of the project given) then ask questions here :) & search the web for solutions and patterns.
If all that fails and you can clearly solve your problem with another technology, then look at moving but make sure your customer is aware of how that's going to affect you timeframes.
When you've implemented this project and have some spare time, if there's a new direction you'd like to explore then use this project as your base and set to work without the stress of a deadline.
That's my 2p worth... good luck!

When developing a CRUD application such as this, you may be required to reinvent the wheel a little if starting from scratch. Many parts of your project are not unique to the project. E.g authentication, database access, form manipulation etc.
If getting things done is important to you it may be important to give your project a kick start and stop you wasting too much time.
Use a coding framework
Frameworks often have a lot of functionality ready for use straight out of the box.
Options may include Django, Ruby on Rails, Joomla, CakePHP, CodeIgniter.
Hack a tried and tested application
Open source projects are often quite easy to mould to your needs. Drupal and Joomla are CMS products which can be used in a wide variety of ways. If your book-tracking drupal module is any good, maybe you could go on to offer it as an open source plugin?
Use a currently available app in a new way
Your app seems to be tracking the status of items added to a database. How about using software designed for tracking other types of items. E.g. bug tracking software, project management to-do list software or customer relationship management software?

Well, as everyone has already said, if you already know PHP, that's got to be awfully tempting.
But it sounds simple enough that something like Django might save you a lot of time: its built-in admin interface could be used for the "update" side of the job, so all you'd need to template up is the "read" side, which is pretty easy.

I suggest you too look at Viravis.
