We have several webapps based in Wordpress and Codeigniter, which are based on different servers but under the same domain (ie: intranet.something.local) and most of them use Active Directory login credentials.
For Wordpress, I'm using a plugin called Active Directory Integration to log in with these credentials and it's working perfectly after configuring openLDAP.
The thing is, our client asked us to have a single log on for every app, meaning that once I'm logged into Wordpress, I should be logged in when I go to another app, that uses the same login user and password.
Is there a possible way to do this? And if so, where should I start?
I believe, that is possible in multiple ways..
Setup Single Sign On in your apps
Use a script which automatically copies User data from a web app, and then using that information creates user login to the other apps..Idea is to let user register for one site, and based on that information, register him to other sites automatically
May be, some sort of Database sharing be possible, but that would be really really a tough job, still Possible (I believe, in Computer Science, nothing is impossible forever)
