IBM Data and AI Ideas Portal for Customers

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.

.net Trusted Connection String for DB2 Z/OS

In an attempt to build a .net program that takes advantage of ID propagation in Z/OS for RACF. We are trying to connect to DB2 on Z/OS from a Windows client using DB2 connect. Specifically, we are trying to create a trusted connection with the IBM Data Server Provider for .NET.

The problem that we are having is that DB2 doesn't understand that we are passing it a distributed ID. This is because in order for DB2 to understand that a distributed ID is being used a registry must be passed as well. There is no keyword option for this in the connect string for .net.
Example from:


We have all the other pieces turned on and functioning. We have verified with IBM that the trusted context is setup in DB2 properly. The RACF ID propagation facility class has been turned and the ID mapped. This is the one piece that we are missing.

Per the Redbook:
Identity Propagation for Z/OS page 35
DB2 10 for z/OS Identity Propagation works only in a trusted context. The end user's identity
consists of a distinguished name and registry name. Using a trusted connection, DB2 for
z/OS detects the registry name and allows the distributed identity to be passed onto RACF to
be mapped.

Also page 36:
The registry name is not verified by RACF, however, it must be supplied by the distributed
application, otherwise DB2 will not recognize the distributed identity and will be treated as a
normal RACF user ID.

Which is what we believe we are seeing when currently trying to connect without passing a registry. The program will work when passing a RACF ID, but when passing a distributed ID after the trusted connection has been made it tries to verify that the ID being passed is a RACF ID. Instead, it should be looking in the RACF map class for this distributed ID to be mapped to a RACF ID.

We need the ability to pass a registry to DB2 so that it will understand we are passing it a distributed ID. This ability is already available in Java.
