IBM Power Ideas Portal
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 this portal to enhance a Power product or service. Take a look at ideas others have posted and upvote them if they matter to you,
Post an idea
Upvote ideas and add comments to ideas that matter most to you
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 Power teams 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.

An idea for the implementation could be to use RBAC domains. For example, if a user has a specific RBAC domain assigned, the RBAC domain could limit the list of users that a requester can SU to. A stanza-based file could list the stanza of an RBAC domain name and the values could be user ids. When a script/executable that is a privileged command in RBAC uses needs to su into a user account, the Kernel could check if the requester has a domain assigned that allows the requester to switch to the target user.
Example:
/etc/security/privsu
domainsu1:
sapadmin
fwadmin
domainsu2:
webadmin
dbadmin
A kernel privilege could be created, i.e. PV_SU_LIMIT, that is assigned as an innate privilege to a privileged command.
If a calling user runs the privileged command and the command performs a su, the domain is checked and if the target user of the su operation is listed in one of the assigned domains, the su succeeds.
