By "Windows Authentication", are you referring to NTLM?


Gambit 

I am using Incdy 9.0.18.

I try 2 things as followings but they don't work.

1. By using
    http->Request->Username = "username";
    http->Request->Password = "password";

2. By Using
http->OnAuthorization = MyHandler;
++++
void __fastcall MyHandler(TObject *Sender, TIdAuthentication 
*Authentication, bool &Handled)
{
  Authentication->Username = "username";
  Authentication->Password = "password";

  Handled = true;
}

Anyway, if I change website on IIS to Basic Authentication, ther work.

But when I use Windows Authentication, error 401 found.

To use an Authentication scheme with TIdHTTP, one of the following things 
must be done:

1) register the desired TIdAuthentication... classes via the 
RegisterAuthenticationMethod() function at program startup.  This allows 
TIdHTTP to select auth schemes automatically.

2) use the OnSelectAuthorization event to create a suitable 
TIdAuthentication... object instance for one of the auth schemes that the 
server supports (provided in the AuthInfo parameter of the event handler)

3) if you know the exact auth scheme that the server will be using ahead of 
time, you can assign a suitable TIdAuthentication... object instance to the 
Request->Authentication property before sending a request.


Gambit 

I try to use as followinng code but it generates error after I create 
variable "IdNTLMAuthentication":

The error is "Operation aborted".

Where am I wrong?

+++++

TIdNTLMAuthentication *IdNTLMAuthentication = new TIdNTLMAuthentication();

// Generates error "Operation aborted"

IdNTLMAuthentication->Username = "user";
IdNTLMAuthentication->Password = "password";
http->Request->Authentication = IdNTLMAuthentication;

On which line exactly?

Don't do that.  Use TIdHTTP's properties instead:

    http->Request->Authentication = new TIdNTLMAuthentication();
    http->Request->Username = "user";
    http->Request->Password = "password";


Gambit 

Hi Gambit,

Thanks for your help.

But when I call

http->Request->Authentication = new TIdNTLMAuthentication();

It still found the error "Operation aborted." in Exception (ex.Message) 
after I have try/catch

try {
http->Request->Authentication = new TIdNTLMAuthentication();
}
catch (ex as Exception) {
  ' Error Found in ex.Message()
}

What is the actual class type of the exception?

> catch (ex as Exception) {

That is not a valid statement.  You need to catch exceptions by reference,
preferrably by 'const' reference, ie:

    catch (const Exception &ex)


Gambit

I have already known the problem and solved. The first problem is OpenSSL is 
not installed.

Now I thought I can use NTLM Authentication.

BUT it still have the error code returned from Web Server is "HTTP Error 
401.2 - Unauthorized"

I need just to find the way to Get HTTP Page from selected Windows 
Authentication from IIS server.

How can I do?

Then either your credentials are not correct, or the server does not want
NTLM authentication to begin with.  Can you show a log from a packet capture
of the original HTTP request and server reply?


Gambit

I think it's NOT WORK.

Could you have a simple code to use TIdHttp with Windows Authentication?

I need to Get HTTP page from IIS with having Windows Authentication.

I'm surrender.

You did not provide the data I asked for.  Please do so.  I cannot help you 
further without it.  I need to see what the server is actually asking your 
client for.

I already have.


Gambit 

I try to find program to capture HTTP header and fond it has nothing in HTTP 
header when I call TIdNTLMAuthentication.

Here is the HTTP Header when request:
GET /default.html HTTP/1.1
Host: 127.0.0.1
Accept: text/html, */*
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0)

Here is the HTTP Header when response:
HTTP/1.1 401 Unauthorized
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
X-Powered-By: ASP.NET
Date: Wed, 13 Feb 2008 21:43:01 GMT
Content-Length: 3481

I supprise in request caused by it should have more tag liked 
"Authorization: NTLM TlRMTVNTUAA..........." but it's gone.

If you have a simple completed code for Windows Authentication. Pls send me 
at j_aladin@hotmail.com that is appreaciated.

The server is asking for "Negotiate" first.  You have to use 
TIdSSPINTLMAuthentication instead of TIdNTLMAuthentication for that. 
However, since the server is also stating that "NTLM" is supported, then 
TIdNTLMAuthentication should have worked ok.  Something else has to be 
happening.  Since TIdNTLMAuthentication's constructor loads the OpenSSL 
DLLs, you probably don't have the right version installed.  That is the only 
thing I can think of that would cause the constructor to throw an exception.

TIdHTTP does not send authorization credentials unless the server 
explicitally asks for them first.  In this case, you sent a request, and the 
server replied asking for the credentials.  There should have been a second 
request sent automatically after that which included the credentials that 
TIdNTLMAuthentication generates.  Of course, if you can't create the 
TIdNTLMAuthentication object to begin with, then it won't be available to 
generate that data.


Gambit

I try changing to use TIdSSPINTLMAuthentication instead BUT caused by the 
package of Indy 9.0.xx does not provide for C++.

I have to add IdAuthenticationSSPI.pas and IdSSPI.pas in Indy60.dpk first 
and the build new package which it works OK, no error found.

But when I complied program by including <IdAuthenticationSSPI.hpp> there 
generates too many errors and I cannot fix them (Most in file IdSSPI.hpp and 
IdAuthenticationSSPI.hpp which automatically generated from compiler).

Example error:
IdSSPI.hpp(866): E2040 Declaration terminated incorrectly.
IdSSPI.hpp(867): E2040 Declaration terminated incorrectly.
IdAuthenticationSSPI.hpp(866): E2238 Multiple declaration for '_fastcall 
ESSPIException::ESSPIException(AnsiString,int)'

Is this a right way to handle this task?
