Re: Connecting to non-standard HTTP ports with authorization

Just a little update,
-1012 is NSURLErrorUserCancelledAuthentication, and that caught my suspicioun that perhaps data got sent anyway. So fire up Wireshark, and sure enough, my request is sent:

GET /Pages/Default.aspx HTTP/1.1
User-Agent: (myApp/0.1 (myApp)
Accept: */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
Connection: keep-alive
Host: 192.168.0.5:42334

And a 401 is passed back, with NTLM authentication, not Basic. Sorry about that, but it doesn't really change anything with my problem as far as I know:

HTTP/1.1 401 Unauthorized
Content-Length: 1656
Content-Type: text/html
Server: Microsoft-IIS/6.0
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM
MicrosoftSharePointTeamServices: 12.0.0.4518
X-Powered-By: ASP.NET
Date: Mon, 30 Jun 2008 12:55:40 GMT

And then of course it fails again, and the -1012 is returned saying the user cancled while in fact, no authentication info was sent. So my question is: how can I make a correct NTLM authentication via HTTP, because what I'm doing right now seems to be incorrect

Cheers

Hi,
I'm trying to connect to a server that requires HTTP authentication and that lives on a non-standard port. I've written a little bit of code that works great when it tries to connect to a server on port 80, but I get an error when connecting to the non-standard port, and I get it without it trying to connect at all:

{
NSErrorFailingURLKey = http://192.168.0.5:42334/;
NSErrorFailingURLStringKey = "http://192.168.0.5:42334/";;
NSUnderlyingError = Error Domain=kCFErrorDomainCFNetwork Code=-1012 UserInfo=0x1f0b40 "Operation could not be completed. (kCFErrorDomainCFNetwork error -1012.)";
}


Here is my code:

+ (void) test {
NSString *host = @"http://192.168.0.5:42334/";;
NSString *username = @"someuser";
NSString *password = @"somepass";
int port = 42334;

NSURLCredential *newCredential =[NSURLCredential credentialWithUser:username password:password persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *space = [[NSURLProtectionSpace alloc] initWithHost:host port:port protocol:@"http" realm:nil authenticationMethod:nil];

NSURLCredentialStorage *store = [NSURLCredentialStorage sharedCredentialStorage];
[store setCredential:newCredential forProtectionSpace:space];

NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:host] cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:30];

NSURLResponse *response;
NSError *error;
NSData *returnData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];

	if(error) {
		NSLog(@"test error: %@", error);
		NSLog(@"test userinfo: %@", [error userInfo]);
	} else {
		NSLog(@"test response: %@", response);
		NSLog(@"test result: %d", returnData);
	}
}

What am I doing wrong? How should I modify the code to connect correctly? Also, do I need to do anything specific if I want to support servers that require NTLM or Digest authentication rather than Basic? Where can I look up errorcode -1012?

Cheers
