CA2123 and SharePoint 2010 application page

I have a SP2010 application page to which I want all authenticated users to be able to navigate.

public partial class AllWorkspacesTreeDisplay : LayoutsPageBase
    {
        protected override void OnLoadComplete(EventArgs e)
        {
            base.OnLoadComplete(e);

            // DO SOME WORK    
	}
}

When running Code Analysis on this I get the following

CA2123 Override link demands should be identical to base
Add the following security attribute to 'AllWorkspacesTreeDisplay.OnLoadComplete(EventArgs)' in order to match a LinkDemand on base method 'LayoutsPageBase.OnLoadComplete(EventArgs)':  [PermissionSet(SecurityAction.LinkDemand, Name = "FullTrust")].
xxx.xxx.WorkSpace - AllWorkspaces.aspx.cs (Line 12)

Bearing in mind I want all authenticated users to be able to access that page (hence inheriting from LayoutsPageBase), what should I do?
