我有一个不寻常的情况。

我正在处理安装在 Windows Server 2008 R2 域控制器机器上的 IIS 7.5。

我正在尝试编写一个在该 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 应用程序的文件夹的那一刻。

在做了一些研究后，我发现我需要为以下用户帐户分配访问权限：

IIS 应用程序池\[应用程序池名称]

所以我想出了这个代码：

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上述方法，否则上述方法有效。它抛出这个异常：

部分或全部身份参考无法翻译。

我可以分配这些所需权限的唯一方法是从命令行手动执行此操作：

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

知道如何icacls用 C# 做这些事情吗？

您不应该按照我的 Microsoft 的建议在域控制器上运行 IIS，因为这可能会导致安全和权限问题。

如果你真的想这样做，你应该使用域帐户来运行应用程序池，而不是集成的 IIS Apppool。这不起作用，因为域控制器没有本地帐户并且 IIS APPool 帐户是本地的。

我想我是使用非托管方法得到的。在 C# 中结果有点难看，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

更好的是，创建您自己的使用给定凭证运行的应用程序池。并为 Web 应用程序安装文件夹上的给定凭据（用户名）分配权限。
