Hurray!! After a tiresome work on saturday CAS-Central Authentication System popularly called Single Sign On came into effect. We have been working on this for about three months starting from December. We started this on December without a single hint about what we are supposed to do. It was like walking in the dark forest, knowing nothing about our next step. But all went fine under seniors guidance and here we are, at the edge of a finishing it. Still a lot of loose ends to be tied up and everything would be fine once all are done. Lot of problems are sure to occur. Hope everything goes fine without problem.
