I solved my problem one issues though When we login to the jboss portal using a username and then when we browse to the CMS portlet it again asks for relogin and this time we can change the user. How can I make a single sign on for both the CMS and the Portal so nly the same user who logged into the portal in the first place can access the CMS for that user??
