Trying to run system-config-samba in terminal gives the following:

    mainWindow.MainWindow(debug_flag)
  File "/usr/share/system-config-samba/mainWindow.py", line 121, in __init__
    self.basic_preferences_win = basicPreferencesWin.BasicPreferencesWin(self, self.xml, self.samba_data, self.samba_backend, self.main_window)
  File "/usr/share/system-config-samba/basicPreferencesWin.py", line 97, in __init__
    self.admin = libuser.admin()
SystemError: could not open configuration file `/etc/libuser.conf': No such file or directory
