powershell - 将对象复制到具有更改值的新对象

Question

需要获取ACL对象并替换Access.IdentityReference.Value并保持其余对象不变，因此我可以将Set-Acl应用于另一个系统。

$acl = Get-Acl -Path "C:\Temp"
$h = New-Object -TypeName PSObject
ForEach-Object -InputObject $acl -Process {
    if ($_.Access.IdentityReference.Value -contains "BUILTIN\Users") {
        "found"
        $h += @($_.Access.IdentityReference.Value.Replace("BUILTIN\Users", "new\name"))
    } else {
        $h += @($_)
    }
}
$h.Access

我有很多方法可以做到这一点，而我能够获得的最好的方法就是找到并替换目标值，但丢失了其余的原始对象。

编辑:尝试此代码时的:

$acl = Get-Acl -Path 'C:\Temp'

$ace = $acl.Access | Where-Object { $_.IdentityReference -eq 'BUILTIN\Users' }
$newAce = New-Object System.Security.AccessControl.FileSystemAccessRule (
    'new\name',
    $ace.FileSystemRights,
    $ace.InheritanceFlags,
    $ace.PropagationFlags,
    $ace.AccessControlType
)
$acl.RemoveAccessRule($ace)
$acl.AddAccessRule($newAce)

Set-Acl -Path 'C:\Temp' -AclObject $acl

我收到以下错误:

Exception calling "AddAccessRule" with "1" argument(s): "Some or all identityreferences could not be translated."At line:12 char:1+ $acl.AddAccessRule($newAce)+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~     + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException     + FullyQualifiedErrorId : IdentityNotMappedException

Edit2: New script, but not quite there yet:

$Ssid = "S-1-5-21-2214593661-3374179426-1523454523-1133"
$Tsid = "S-1-5-21-2227185791-3254421074-497073356-1005"
$Spath = "\\clw01\dept\CLW_Site"
$Tpath = "\\clw03\dept\CLW_Site"

$acl = Get-Acl -Path $Spath

$ace = $acl.Access | Where-Object { $_.IdentityReference -eq $Ssid }
$newAce = New-Object System.Security.AccessControl.FileSystemAccessRule (
    $Tsid,
    $ace.FileSystemRights,
    $ace.InheritanceFlags,
    $ace.PropagationFlags,
    $ace.AccessControlType
)
$acl.RemoveAccessRule($ace)
$acl.AddAccessRule($newAce)

Set-Acl -Path $Tpath -AclObject $acl

我收到以下错误:

您不能替换现有ACE上的标识引用，而需要用新的ACE替换整个ACE。

$acl = Get-Acl -Path 'C:\Temp'

$ace = $acl.Access | Where-Object { $_.IdentityReference -eq 'BUILTIN\Users' }
$newAce = New-Object System.Security.AccessControl.FileSystemAccessRule (
    'new\name',
    $ace.FileSystemRights,
    $ace.InheritanceFlags,
    $ace.PropagationFlags,
    $ace.AccessControlType
)
$acl.RemoveAccessRule($ace)
$acl.AddAccessRule($newAce)

Set-Acl -Path 'C:\Temp' -AclObject $acl
