CodeIgniter base project

If you are starting a CodeIgniter project, I’d recommend using

https://github.com/kenjis/codeigniter-composer-installer

as your base.  Composer makes things so much easier.  Then for User management and authentication use Ion_Auth (GitHub)

If you need LDAP, Adldap2 is really easy to use.

From the kenji github page, you can find a lot of other packages.  The other package I’ve used a lot of is the REST Server.  However, if all you need to do is a REST Server I’d recommend using NodeJS.
