Single Sign on between Java Application and COGNOS Report

[nsaha]

Hi Gurus,

Can you please do me a favour?Below here is the problem which I am facing.Please help.

There are two subsystems. One is a web based Java  application and the other a Cognos reporting tool. Currently, both these applications provide individual login pages (LDAP authentication is used)that allow the users to perform their activities, as per the roles defined in the system. Java EE users can directly login to the Java EE application using its login page. Similarly, the Cognos users can login to the Portal using its login page by supplying their intranet ID credentials.

There is a requirement, wherein the users of the Java EE application should be able to view the Cognos reports by clicking on a URL link in the Java EE web application. At present, clicking this URL would open the Cognos portal prompting for user credentials.

I am expecting a solution that would help us bypass the Cognos Portal login page, when clicked on the URL. This will help the users who have logged in the Java EE application to view the Cognos reports on a new web page with same LDAP role without having to logging in again
