Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Cloud Pak for Data can integrate with ISAM with virtual junction for Single-Sign-On

Some customers would like to integrate Cloud Pak for Data with ISAM which enabled virtual junction for Single-Sign-On.

These customers have the security requirement that CP4D must be deployed in App tier and can't be access directly from user workstation. Virtual junction (Reverse Proxy) in ISAM is setup to handle the tier requirement so that all traffic move from user workstation --> Reverse Proxy (Web Tier) --> (CP4D App Tier).

Because of above requirement, all the http requests/responses from client browser goes via virtual junction (reverse proxy) of ISAM. The virtual junction server authenticate all the http requests using session cookie. And it returns login page if it does not find the session cookie. As some services on Cloud Pak for Data, e.g. WKC, are taking Bearer token for the authentication rather than session cookie, this is breaking the integration.

But for customer, they are complaining that why Cloud Pak for Data can't integrate with ISAM with virtual junction even they are both from IBM. And they asked IBM for providing such kind of integration as an official solution.

For more background and information, you can refer to this git issue

It would be good to start from WKC as customer already opened tickets for such requirements.

    Hi Alvin, my apologies for not responding earlier. I inquired with the CPD team and they provided the following information:

    CPD (Zen/Lite) from a platform perspective already works with Virtual Junction turned on. Some requests in the "Unified governance" user experiences fail to leverage a cookie based mechanism from the browser - and that causes a problem with Virtual Junction.

    Please see on some pointers on how to resolve this

    Hope this helps.
