I can really use some help here....
I wanna share the userbase of a site with other sites.
The idea is that a user has a main useraccount on aaa.com. There they update the profile, password and there I will add additional stuff like credits and maybe even paid subscriptions.
Then I want other sites to use the data of that userbase. For example on shopbbb.com users can login with their account of aaa.com and pay stuff with credits from their aaa.com account.
This is a few steps ahead... For now i'm looking for a way to get users that are logged into aaa.com to login to bbb.com with their aaa.com account.
It's a bit like the janrain feature where you can login to different sites using your google, yahoo, twitter or some other accounts.
My idea is that people can also login using their aaa.com account.
How can I set this up?
I have been searching for 'openID provider' and 'OAuth SSO' but couldn't find anything that looks right (or am I not looking correct?).
I really, really appreciate some help....
Thank's in advance!
