Problems Logging On to Cognos Portlets
There are several reasons why users with valid portal user IDs and passwords may not be able to log on to Cognos Portlets.
If IBM Cognos 8 is configured to use more than one authentication namespace, you must install a separate IBM Cognos 8 gateway and configure it to use the namespace for portal users.
You must also change the CPS connection point in the Cognos portlets:
For IBM Websphere, change the CPS Endpoint parameter in the portlet application.
IBM WebSphere Portal
If you use the IBM Websphere portal, ensure that the following is true.
The credentials for the portal user are available in the IBM Cognos 8 authentication namespace.
The server running the portal and the server running IBM Cognos 8 are both configured to use the IBM WebSphere Application server.
Both application servers are configured for single signon using one of the supported Active Credentials objects: HttpBasicAuth, LtpaToken, SiteMinderToken, or WebSealToken.
The selected Active Credentials method is indicated in the parameters for the Cognos portlet application.
If using Ltpa token as an Active Credentials object, the IBM Cognos 8 URL entry point is secured in IBM Cognos 8.
Create a secure URL to access the dispatcher servlet or servlet gateway.[/quote]
I apologize for the delayed response.
Thank you for your reply.
I’m pretty new to this Cognos, so took some time to understand your comments and then tried to validate it with my Cognos Environment.
So let me explain my cognos environment and what I’m trying to achieve.
Note: I don’t have any portlets here, Neither WebSphere Portal Nor Cognos Portlets
I’m trying to achieve Single Sign On between WebSphere App Server 6.1.x (WAS 6.1.x) and Cognos 8.4 running on Tomcat.
The primary Cognos 8.4 install is distributed between three different physical machines as described below
Gateway Machine: The default gateway i.e. Apache HTTP Server, Cognos Gateway Component
Content Manager Machine: Cognos Content Manager and other cognos components
Database Machine: Cognos database
Cognos is configured with Two Authentication Sources, 1. Active Directory and 2. SharedSecret
Some of my Web Applications are running on WAS 6.1.x (this is on a different machine altogether so lets say WAS Machine)
and I’ve to enable Single Sign On between my Web Applications running on WAS 6.1.x and Applications running on Cognos 8.4.
To achieve this, I installed Cognos Gateway Component on my WAS Machine and generated the ServletGateway EAR application, deployed it, secured it (basic authentication) and enabled Single Sign On with LTPA.
I configured Cognos Gateway component running on my WAS Machine with ‘Active Directory’ Namespace ID.
I configured my WAS to use the same Active Directory i.e. the one used by my Cognos.
Note: My WAS does not have any other Cognos related applications deployed except ServletGateway EAR Application.
The trouble started as I want to use only ‘Active Directory’ for all the users who use ServletGateway gateway.
So as explained in my initial post, with the this configuration when ever I hit the url
I get a blank page.
Please let me know if you need further details to help me address this issue.
I appreciate your time and help.
Thanks & Regards
