I am seeking your advice regarding development of single sign on solution.
The existing scenario is as follows.
We have 5 different WEB APPLICATIONS running on production server which have their respective login forms and underlying authentication and authorization logic.Now we have to come up with a single sign on solution for these underlying web applications.
I don't know exactly how i should proceed.I mean which API's i should look for and what would be the design for it.
I have googled a lot and tried my hands on JAAS also (just got a feel by developing a simple command prompt based trial app) but not able to find a clear cut working path.
