You will run into issue when you deploy opensso.war on
Glassfish v3 prelude (I think even Sun Web Server 7 update 3)
After you have successfully login to console, the request
is redirected back to the Login page.
Several people have already reported this problem.
Here is what happen. OpenSSO sets a cookie with value containing “=”. and Glassfish truncates the cookie value. Since OpenSSO server cannot get the entire cookie value, SSO Token cannot be created.
An issue is filed on Glassfish.
