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

Start by posting 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 offering manager 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 a 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.

If you encounter any issues accessing the Ideas portals, please send email describing the issue to for resolution.

Provide support for Kerberos Constrained Delegation (S4U2Proxy, S4U2Self) in WebSphere Full Profile

With JDK 8 the S4U2Proxy and S4U2Self mechanisms are implemented in the GSSApi for delegated access with credentials of the client to backend servers with Kerberos.


Currently WebSphere Application Server 8.5.5 and 9beta do not provide APIs or Support for delegating credentials via S4U2Proxy and S4U2Self in a Kerberos authenticated Installation.

In Liberty Profile the S4U2Proxy, S4U2Self mechanisms are supported but this is not the case in Full Profile and seems not to be provided with the new Version 9 of Full Profile.

It would be very helpful, if the Full Profile supports constrained delegation too.
