SYMPTOMS

Consider the following scenario:
  • You publish a Web site in Microsoft Internet Security and Acceleration (ISA) Server 2006.
  • In the Web listener, ISA Server is configured to use forms-based authentication to authenticate client requests.
  • ISA Server is configured to present an RSA SecurID form to the client users.
  • The RSA SecurID logon form is customized for mobile devices by using XHTML-Mobile Profile (XHTML-MP) and cHTML.
However, the RSA SecurID logon form may not work. After a user submits the customized logon form from a mobile device, the Web browser does not open the desired Web site.

CAUSE

If you use forms-based authentication and the RSA SecurID authentication scheme to publish a Web site, the user receives a logon form after the user logs on successfully. This logon form redirects the Web browser to the original URL that the user accesses. ISA Server uses a Refresh header to implement the redirection. However, some devices may not understand this header.

RESOLUTION

How to enable KB939849

  1. Apply the hotfix that is described in the following Microsoft Knowledge Base article:
    940250 Description of the ISA Server 2006 hotfix package: July 16, 2007
  2. Start Notepad.
  3. Copy the following script into a Notepad file.
    Const SE_VPS_GUID = "{143F5698-103B-12D4-FF34-1F34767DEabc}"
    Const SE_VPS_NAME = "Use302ForSecureIDRedirect"
    Const SE_VPS_VALUE = true
    
    Sub SetValue()
    
        ' Create the root obect.
        Dim root  ' The FPCLib.FPC root object
        Set root = CreateObject("FPC.Root")
    
        'Declare the other objects needed.
        Dim array       ' An FPCArray object
        Dim VendorSets  ' An FPCVendorParametersSets collection
        Dim VendorSet   ' An FPCVendorParametersSet object
    
        ' Get references to the array object
        ' and the network rules collection.
        Set array = root.GetContainingArray
        Set VendorSets = array.VendorParametersSets
    
        On Error Resume Next
        Set VendorSet = VendorSets.Item( SE_VPS_GUID )
    
        If Err.Number <> 0 Then
            Err.Clear
    
            ' Add the item
            Set VendorSet = VendorSets.Add( SE_VPS_GUID )
            CheckError
            WScript.Echo "New VendorSet added... " & VendorSet.Name
    
        Else
            WScript.Echo "Existing VendorSet found... value- " &  VendorSet.Value(SE_VPS_NAME)
        End If
    
        if VendorSet.Value(SE_VPS_NAME) <> SE_VPS_VALUE Then
    
            Err.Clear
            VendorSet.Value(SE_VPS_NAME) = SE_VPS_VALUE
    
            If Err.Number <> 0 Then
                CheckError
            Else
                VendorSets.Save false, true
                CheckError
    
                If Err.Number = 0 Then
                    WScript.Echo "Done with " & SE_VPS_NAME & ", saved!"
                End If
            End If
        Else
            WScript.Echo "Done with " & SE_VPS_NAME & ", no change!"
        End If
    
    End Sub
    
    Sub CheckError()
    
        If Err.Number <> 0 Then
            WScript.Echo "An error occurred: 0x" & Hex(Err.Number) & " " & Err.Description
            Err.Clear
        End If
    
    End Sub
    
    SetValue
    
  4. Save the file as a Microsoft Visual Basic script file by using the .vbs file name extension. For example, use the following name to save the file:
    EnableKB939849.vbs
  5. Start a command prompt, move to the location where you saved the EnableKB939849.vbs file, and then run the following command:
    cscript EnableKB939849.vbs
