Cognos 10.2/WAS 8 Single Sign On with Websphere Portal 7

[kkirnbauer]

Hello,

first i want to describe my environment:

Cognos 10.2 runs on Websphere Application Server 8 and is connected to our Active Directory with Cognos Configuration.

On the other hand, we have a Websphere Portal 7 Express, which provides all the content for our company. (For instance: there is an Alphablox application with another WAS, with LTPA Single Sign On works perfectly as IFRAME in the Portal)

Now we want also share Cognos to our users with Single Sign On as IFRAME in our Portal.

I have tried several approaches (IdentityMapping=SingleSignOnOption, ...), but i always get the Login Screen from Cognos.

The 2 WAS (Portal and Cognos) have a shared secret (LPTA) and in the Cognos Configuration i have enabled the Identity Mapping.

Unfortunately, it doesn't work.

Can somebody help me with that problem?

Kind Regards
Klaus
