FIX: Your application cannot load resources from a satellite assembly if the impersonated user account does not have permissions to access the application .config file in the .NET Framework 1.1 Service Pack 1

Article ID: 894092

Article Last Modified on 12/3/2007

APPLIES TO

Microsoft .NET Framework 1.1 Service Pack 1
Microsoft Office SharePoint Portal Server 2003

SYMPTOMS

When you use impersonation in your Microsoft .NET Framework 1.1 Service Pack 1 (SP1) based application and the impersonated user account does not have permissions to access the application .config file, the application cannot load resources from satellite assemblies.

When this problem occurs, neutral resources are returned instead of the resources that are contained in the satellite assembly.

Also, in non-English versions of Microsoft Office SharePoint Portal Server 2003, the Site Settings page is displayed in English.

Note This behavior might occur in other non-English versions of SharePoint Portal Server 2003 that have not yet been reported.

Steps to reproduce the problem

Create satellite assembly. To do this, follow these steps:
1. Create a text file that is named MyRes.txt, and then add the following text to the file:
```
TEST1 = "TEST1 for Neutral resource"
```
2. Create a resource file that is named MyRes.resources by running the following command:
  
  resgen MyRes.txt MyRes.resources
3. Create a resource assembly that is named MyRes.dll by running the following command:
  
  al /t:lib /embed:MyRes.resources /culture:neutral /out:MyRes.dll
4. Create a folder in your project that is named ja-jp to store another culture.
5. Create a text file that is named MyRes.txt in the new folder, and then add the following text to the file:
```
TEST1 = "TEST1 for Japanese"
```
6. Create a resource file that is named MyRes.ja-jp.resources in the new folder by running the following command:
  
  resgen MyRes.txt MyRes.ja-jp.resources
7. Create a resource assembly that is named MyRes.resource.dll by running the following command:
  
  al /t:lib /embed:MyRes.ja-jp.resources /culture:ja-jp /out:MyRes.resources.dll

Create a console application. To do this, follow these steps:

Create a Microsoft Visual C# source file that is named Test.cs, and then add the following code example to the file.

// Test.cs
// --------------------------------------------
using System;
using System.Runtime.InteropServices;
using System.Security.Principal;
using System.Security.Permissions;

class Class1
{
    [DllImport("advapi32.dll", SetLastError=true)]
    public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);

    [DllImport("kernel32.dll", CharSet=CharSet.Auto)]
    public extern static bool CloseHandle(IntPtr handle);

    [DllImport("advapi32.dll", CharSet=CharSet.Auto, SetLastError=true)]
    public extern static bool DuplicateToken(IntPtr ExistingTokenHandle, int SECURITY_IMPERSONATION_LEVEL, ref IntPtr DuplicateTokenHandle);

    static void Main(string[] args)
    {
        string str;

        // Load MyRes.dll and initialize ResouceManager.
        System.Reflection.Assembly asm = System.Reflection.Assembly.Load("MyRes");
        System.Resources.ResourceManager res = new System.Resources.ResourceManager("MyRes", asm);

        // Perform impersonation.
        IntPtr tokenHandle = new IntPtr(0);
        IntPtr dupeTokenHandle = new IntPtr(0);
            
        string UserName, Password;
        UserName = "testuser";  // Change the user name and password correctly.
        Password = "testuser";  // Change the user name and password correctly.
  
        const int LOGON32_PROVIDER_DEFAULT = 0;
        const int LOGON32_LOGON_INTERACTIVE = 2;
        const int SecurityImpersonation = 2;

        tokenHandle = IntPtr.Zero;
        dupeTokenHandle = IntPtr.Zero;

        bool returnValue = LogonUser(UserName, ".", Password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT,ref tokenHandle);
        bool retVal = DuplicateToken(tokenHandle, SecurityImpersonation, ref dupeTokenHandle);
            
        WindowsIdentity newId = new WindowsIdentity(dupeTokenHandle);
        WindowsImpersonationContext impersonatedUser = newId.Impersonate();

        // Try to obtain the "ja-jp" string from the satellite assembly.
        str = res.GetString("TEST1", new System.Globalization.CultureInfo("ja-jp"));

        // Determine the result of the ResouceManager.GetString method.
        Console.WriteLine(str);

        // Determine the current user name.
        str = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
        Console.WriteLine(str);


        impersonatedUser.Undo();

        if (tokenHandle != IntPtr.Zero)
            CloseHandle(tokenHandle);
        if (dupeTokenHandle != IntPtr.Zero) 
            CloseHandle(dupeTokenHandle);
    }
}

Create the Test.exe application. To do this, compile Test.cs by using the following command:

csc test.cs
Create a empty Test.exe.config file in the same folder as the Test.exe application.
Make sure that MyRes.dll is in the same folder as the Test.exe application.
In the same folder as the Test.exe application, create a subfolder that is named ja-jp.
Copy the MyRes.resource.dll file to the ja-jp subfolder.

Create a new user account. To do this, follow these steps:
1. Create a new user account that is named testuser, and then set the password to testuser.
2. Add the testuser user account to the Local Administrator Group.
3. Change the file permission on the Test.exe.config file to Deny all for the testuser user account.
At a command prompt, run the Test.exe application.

When you run the application, TEST1 for Neutral resource is returned instead of TEST1 for Japanese.
