Question

我正在尝试修改对我域中多台计算机的权限，以便允许它们对跨域进行身份验证。

我的代码很简单，但是我一直遇到错误。

Function Add-ADGroupACL
{
    param([string]$Computername,[string]$Access)
    #Get a reference to the RootDSE of the current domain
    $rootdse = Get-ADRootDSE
    #Get a reference to the current domain
    $domain = Get-ADDomain
    #Create a hashtable to store the GUID value of each extended right in the forest
$extendedrightsmap = @{}
Get-ADObject -SearchBase ($rootdse.ConfigurationNamingContext) -LDAPFilter `
"(&(objectclass=controlAccessRight)(rightsguid=*))" -Properties displayName,rightsGuid | 
% {$extendedrightsmap[$_.displayName]=[System.GUID]$_.rightsGuid}

#Create a hashtable to store the GUID value of each schema class and attribute
$guidmap = @{}
Get-ADObject -SearchBase ($rootdse.SchemaNamingContext) -LDAPFilter `
"(schemaidguid=*)" -Properties lDAPDisplayName,schemaIDGUID | 
% {$guidmap[$_.lDAPDisplayName]=[System.GUID]$_.schemaIDGUID}

    #Get the computer  object for modification on
    $Computer = Get-ADComputer -Identity $Computername

    #get the SID of the group you wish to add to the computer.
    $GroupIdentity = New-Object System.Security.Principal.SecurityIdentifier(Get-ADGroup -Identity $Access).SID

    $computersADPath = "AD:\" + $Computer.DistinguishedName
    $ComputerACL = Get-ACL $computersADPath

    #Create a new rule to add to the object
    $newAccessRule = New-Object System.DirectoryServices.ActiveDirectoryAccessRule(
        $GroupIdentity,"ExtendedRight",
        "Allow", 
        $extendedrightsmap["Allowed To Authenticate"],
        "None")

    $newAccessRule
    #Add the rule to the ACL
    $ComputerACL.AddAccessRule($newAccessRule)
    #Set Rules to the ACL
    Set-Acl -AclObject $ComputerACL -Path $computersADPath
}

我发布了整个功能以使其变得容易。只需这样称呼

Add-ADGroupACL -Computername 'TestComputer' -Access 'TestGroup'

最后是我不断收到的错误消息

Set-Acl：不能将此安全ID分配为此对象的所有者在线：88字符：5 + Set-Acl -AclObject $ ComputerACL -Path $ computersADPath + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~ + CategoryInfo：未指定：（CN = testComputer，OU = Co ... C = subdomain，DC = domain：String）[Set-Acl]，ADException + FullyQualifiedErrorId：ADProvider：SetSecurityDescriptor：ADError，Microsoft.PowerShell.Commands.SetAclCommand

访问规则看起来正确。它显示了这一点。

ActiveDirectoryRights : ExtendedRight 
InheritanceType       : None
ObjectType            : 68b1d179-0d15-4d4f-ab71-46152e79a7bc
InheritedObjectType   : 00000000-0000-0000-0000-000000000000
ObjectFlags           : ObjectAceTypePresent 
AccessControlType     : Allow
IdentityReference     : S-1-5-21-2926237862-3770063950-2320700579-361721 
IsInherited       : False 
InheritanceFlags      : None 
PropagationFlags      : None

任何帮助将不胜感激。谢谢。

对于其他遇到此问题的人，这是解决方案。

基本上，Get-ACL和Set-ACL的工作方式是检索整个ACL。您对ACL进行编辑，然后Set-ACL尝试重写整个ACL。更多信息：https://docs.microsoft.com/en-us/windows/desktop/secauthz/access-control-entries

因此，基本上，您只需要创建一个ACE并将其即时添加到ACL中即可。最好使用DACLS购买

代码：

Function Add-ADGroupACEExtendedRight
{
    param(
        [string]$Computername = $(throw "Computer name must be specified"),
        [string]$Access = $(throw "User or group in which to give acces must be specifieds"),
        [string]$ExtendedRight = $(throw "Extended Right Property Name Required")
    )

    #Get the computer  object for modification on
    $Computer = Get-ADComputer -Identity $Computername

    #get the SID of the group you wish to add to the computer.
    $GroupIdentity = New-Object System.Security.Principal.SecurityIdentifier(Get-ADGroup -Identity $Access).SID

    #Set Permissions
    dsacls $Computer.DistinguishedName /G $GroupIdentity":CA;"$ExtendedRight
}

用法：

Add-ADGroupACEExtendedRight -Computername "TestAsset" -Access "GroupID" -ExtendedRight "Allowed To Authenticate"

您可以在此处添加任何扩展名。有关DACLS的更多信息：https://technet.microsoft.com/pt-pt/library/cc787520%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396

通过Powershell对计算机对象进行SET-ACL
