having to login multiple times with SSO

[tmblanks]

I have tried to integrate several sso frameworks, and I am running into the same problem. When I click on the login button on the top right, I get the sso login page. I am able to authenticate, and it returns me back to the portal login dialog box. I then have to login to the portal login box as well. Correct me if I am wrong, once I login to the sso login, should it pass the credentials to portal? This way I do not have to login twice?

That's typically the goal of SSO frameworks. The portal relies on standard JAAS/JavaEE security principles (ie: a JSESSIONID cookie, by default). So, you'll want to make sure your SSO framework supports this type of configuration or is properly integrated with your portal.

Thanks for your response. Are there any articles that you know of, that can make this a seamless login? I have follwed step by step directions for CAS, JOSSO, and OpenSSO. I am getting the same results for all of them. I would prefer to work with CAS, but if I can get any of them working with a seamless login with portal, that would be great. Any help would be a great help. I am using OpenDS for the authenication.
