           Summary: login manager setting not change when changing settings
                    in System Settings
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: k_b0000 yahoo se


Version:            (using KDE 4.0.4)
Installed from:    Fedora RPMs

when changing the login manager behaviour from
System Settings -> Login manager (as root).
the changes never save, or it is not possible to remove the history from the login manager.

the login manager always shows a few users that have recently logged in.
is should be able to disable this type of history for security reasons.
