Fixes #5884

Summary

• This PR resolves issue #5884 by adding comprehensive documentation for the Manage Users page on Jenkins.io. The page was previously empty, and this contribution provides a detailed guide on managing users in Jenkins, including creating, configuring, modifying, and deleting users.

Changes

• Included step-by-step instructions with screenshots for:

1. Accessing the Manage Users page.
2. Creating a new user.
3. Configuring user settings.
4. Modifying user information.
5. Deleting a user.
6. Added a Troubleshooting section to address common issues.
7. Linked to the Managing Security documentation for authorization details.

Testing

• Tested locally using make run to ensure the documentation renders correctly.
• Verified all links and images are functional.

Please let me know for improvements !

I changed the title to "Users" instead of "Manage Users" because in our Jenkins , I see that name changed to "Users" . Let me know if I am mistaken about it .

that's a good catch @biru-codeastromer since the menu title was changed. Thanks very much. I'll be reviewing this today and will be sure to provide feedback.

Thanks so much for this content @biru-codeastromer. I've provided some smaller suggestions (case, syntax replacement) and alternatives for things like the access control link at the bottom of the page.

I was originally going to include feedback about the "deleting a user" instructions until I realized there were multiple ways to do this. Would it be possible to include the alternative deletion process (going to Manage Jenkins > Users > selecting the trash can icon to the right of the user you want to delete)?

Everything else looks good so far, so thank you again!

Sure , I will add that with needed screenshots and push the changes soon and update you here about that after I complete .

Welcome and thanks for your feedbacks !

Maybe worth pointing out that Jenkins can use many external systems for user management, you can log in to Jenkins with your GitHub, Gitlab, Google, LDAP, ... account as long as you have the respective plugin configured. Information in this article is only relevant if the internal user database is used.

Hi ,
That's a great point! I’ll add a note mentioning this .
I'll update the doc shortly .thanks for your suggestion!

[biru-codeastromer]

I have made the change as requested by you . Let me know how about the position I gave to that note .

I would suggest moving the note about other user management systems to the beginning, because it explains what is the scope of the article. If it's moved there, it should not be part of a warning, just a normal paragraph.
