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.

Why do we have to run "lspasswd" to register windows user's password in LSF ?

Customers hope they don't need to use lspasswd in Windows.

But LSF needs user's password to impersonate user before running user's job on a Windows execution host.

This is due to the designed feature of user authentication in Windows.

Windows needs user's password in order to impersonate user before running user's job on execution windows host. That's to say, LSF needs to logon the windows server to impersonate user. So user password is necessary. This is the limitation of windows host.

Linux user authentication is different. LSF does not need user password to login execution server.

Nevertheless, I hope you will consider whether there is a way to submit the work without using lspasswd in the future.

    There is no practical alternative to this at present.
