如何在域控制器上分配IIS 7.5文件系统访问权限?

我有点不寻常的情况。

我正在处理安装在Windows Server 2008 R2域控制器计算机上的IIS 7.5。

我正在尝试编写一个在IIS上安装我的Web应用程序的C#程序。一切正常,除了我需要将应用程序池的访问权限分配给安装Web应用程序的文件夹。

在完成一些研究后,我发现我需要为以下用户帐户分配访问权限:

  

IIS AppPool \ [AppPoolName]

所以我想出了这段代码:

setFolderPermissions(@"C:\inetpub\www_test1",
    @"IIS AppPool\" + strAppPoolName,
    System.Security.AccessControl.FileSystemRights.Read | System.Security.AccessControl.FileSystemRights.ListDirectory,
    System.Security.AccessControl.AccessControlType.Allow);

public static string setFolderPermissions(string strFolderPath, string sUserName, FileSystemRights rights, AccessControlType access)
{
    DirectoryInfo info = new DirectoryInfo(strFolderPath);

    DirectorySecurity ds = info.GetAccessControl();
    ds.AddAccessRule(new FileSystemAccessRule(sUserName,
                        rights,
                        InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit,
                        PropagationFlags.None,
                        access));

    info.SetAccessControl(ds);
}

除非在域控制器上使用它,否则上述方法有效。它抛出了这个例外:

  

无法翻译部分或全部身份参考。

我分配这些所需权限的唯一方法是从命令行手动执行

C:\Users\Administrator>icacls "C:\inetpub\www_test1" /grant "IIS AppPool\MyAppsoolName":(CI)(OI)(M)

知道怎么用C#做这个icacls的东西吗?

更好的是,创建自己的应用程序池,使用给定的凭据运行。并在Web应用程序安装文件夹中分配给定凭据(用户名)的权限。

您不应该像我所知道的那样在域控制器上运行IIS,因为这可能会导致安全性和权限问题。

如果您确实想这样做,则应使用域帐户运行应用程序池,而不是集成IIS Apppool。这不起作用,因为域控制器没有本地帐户,IIS APPool帐户是本地帐户。

我认为我使用非托管方法得到它。事实证明在C#中有点难看,但这是概念:

uint nOSErr;
if(!(nOSErr = setFolderPermissions(@"C:\inetpub\www_test1", @"IIS AppPool\" + strAppPoolName, OSFileAccess.FILE_GENERIC_READ)))
{
    throw new Exception("Failed to change permissions, error code=" + nOSErr);
}

public static uint setFolderPermissions(string strFolderPath, string strUserName, OSFileAccess access)
{
    //Set folder permissions
    //RETURN:
    //      = 0 if success
    //      = Otherwise error code -- check GetLastError
    uint dwRes = 0;

    try
    {
        IntPtr pZero = IntPtr.Zero;

        IntPtr pSecDesc = pZero;
        IntPtr pDacl = pZero;
        if ((dwRes = GetNamedSecurityInfo(strFolderPath, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.DACL_SECURITY_INFORMATION,
            out pZero, out pZero, out pDacl, out pZero, out pSecDesc)) == ERROR_SUCCESS)
        {
            try
            {
                EXPLICIT_ACCESS ea = new EXPLICIT_ACCESS();

                ea.grfAccessPermissions = access;
                ea.grfAccessMode = AccessMode.GRANT_ACCESS;
                ea.grfInheritance = AceFlags.CONTAINER_INHERIT_ACE | AceFlags.OBJECT_INHERIT_ACE;
                ea.Trustee.MultipleTrusteeOperation = UIntPtr.Zero;
                ea.Trustee.pMultipleTrustee = UIntPtr.Zero;
                ea.Trustee.TrusteeForm = (UIntPtr)(TrusteeForm.TRUSTEE_IS_NAME);
                ea.Trustee.ptstrName = strUserName;

                IntPtr pNewDacl = pZero;
                if((dwRes = SetEntriesInAcl(1, ref ea, pDacl, out pNewDacl)) == ERROR_SUCCESS)
                {
                    try
                    {
                        if ((dwRes = SetNamedSecurityInfo(strFolderPath, SE_OBJECT_TYPE.SE_FILE_OBJECT, SECURITY_INFORMATION.DACL_SECURITY_INFORMATION,
                            IntPtr.Zero, IntPtr.Zero, pNewDacl, IntPtr.Zero)) == ERROR_SUCCESS)
                        {
                            //Done
                        }
                    }
                    finally
                    {
                        //Free mem
                        if (pNewDacl != IntPtr.Zero)

                        }
                    }
                }
            }
            finally
            {
                //Free mem
                if (pSecDesc != IntPtr.Zero)
                {
                    LocalFree(pSecDesc);
