samba share in kde is not working

[Sancho]

Binary package hint: kde-core

I'm using Kubuntu 8.04 LTS Stable amd64. In this OS, I found that I can not use easy Samba sharing. This is my summary:

Action:
  As root:
    - Go to K Menu > System Settings > Sharing > File Sharing
    - Choose "Advanced sharing" and check "Use Samba"
    - Commit (Save configuration)

  As user:
    - Go to his home directory
    - Choose folder to share
    - On right click, choose share
    - Check "Share this folder in the local network"
    - Check "Share with Samba"
    - Check "Public" and "Writable" on "Samba Options"
    - Click OK

Expected:
    - The folder is shared and writable
    - /etc/samba/smb.conf is changed

Fact:
    - The folder is still not shared
    - /etc/samba/smb.conf remains unchanged
