从SharePoint中删除不需要的用户权限

Question

我有一个POSH脚本,用于设置用户对特定文件夹的访问权限,以便读取某些文件.

用户的组被分配到该文件夹​​(恰好是同一个名称).

然后我创建了一个新视图,将其设置为默认值,并告诉它显示所有没有文件夹的文件.

这个脚本已经工作了4个月,但现在有些人想要使用移动视图,我遇到了一个问题.如果用户没有从根目录到相关文件夹的读取权限,则SharePoints移动视图将不显示该文件夹.

例如,用户具有以下权限集:根文件夹上的受限访问权限Alpha文件夹上的受限访问权限读取Alpha下文件夹的访问权限

我需要这样做才能让用户在移动视图中查看.

这是我的代码:

#region Start
# Create Connection to stopwatch diagnostics
[Void][System.Diagnostics.Stopwatch] $sw;
# New Stopwatch object
$sw = New-Object System.Diagnostics.StopWatch;
# Stop any watches that might be running
$sw.Stop();                                         
$sw.Start();

# Which folders to assign
[array]$sections = "Alpha","Bravo","Charlie","Delta";

找到了.试了4个小时的试错,但它确实有效.希望这也有助于其他人.放在$ OpenWeb.GetFolder($ path)之前.Item.Update();

$returnGroups = $OpenWeb.GetFolder($path).Item.RoleAssignments | `
        where {`
         ($_.RoleDefinitionBindings -eq $OpenWeb.RoleDefinitions["Limited Access"]) -and `
         ($_.RoleDefinitionBindings -notcontains $OpenWeb.RoleDefinitions["Read"])`
        };
        if ($returnGroups -not $null)
        {
         foreach ($item in $returnGroups)
         {
          Write-Host "Removing: " $item.Member;
          $OpenWeb.GetFolder($path).Item.RoleAssignments.Remove($spc[$item.Member]);
         }
        }
