Implement Single Sign On

[leoraj]

Hi,
We have a requirement to embed Cognos reports into our company Java based portal.
We are using Active Directory authentication for logging into the portal. The portal has Cognos reports embedded into a tab, we need to implement Single sign on so that the reports are displayed on the portal without prompting the user to log in again to Cognos 8 once they logged into the portal.
Can some one please give a possible solution?

Thanks!
Leo

what authentication provider are you using for your cognos environment? If its the same Active directory setup as your intranet portal, why not just use that?
