Sharepoint silverlightProfileService NTLM authentication from IOS/Objective c

Question

i am attempting to connect to the sharepoint server/_vti_bin/SilverlightProfileService.json/GetUserSLProfileData service to get details about users in the organization.

I am sending my request from objective-c using the ASIHTTPRequest package and am recieving "ERROR Domain=ASIHTTPRequestErrorDomain Code=3 'Authentication Needed'"

My request code:

NSURL *url = [NSURL URLWithString:@"http://aDOMAIN/_vti_bin/SilverlightProfileService.json/GetUserSLProfileData"];
NSString *jsonString = @"{\"AccountNames\": [\"intdev\\aUSER\" ]}";

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:[jsonString  dataUsingEncoding:NSUTF8StringEncoding]];
[request setRequestMethod:@"POST"];

[request addRequestHeader:@"Content-Type" value:@"application/json"];
[request addRequestHeader:@"Expect" value:@"100-continue"];

[request setUsername:@"intdev\\aUSER"];
[request setPassword:@"P@ssw0rd1"];
[request setDomain:@"aDOMAIN"];

[request startSynchronous];
NSError *error = [request error];
if (!error) {
    NSString *response = [request responseString];
    NSLog(@"%@", response);
}
else{
    NSLog(@"%@", error);
}

I have used fiddler to check the requests it IS authenticating with NTLM and i am using the correct username/password/domain.

I am quite stumped and i feel as if i have tried just about everything. Any assistance whatsoever would be much appreciated.

Thanks in advance, Lachlan.

After much investigation I refactored my services to use AFNetworking. It was able to automatically handle all of the authentication.
