Does AFNetworking support NTLM authentication?

Does AFNetworking support NTLM authentication?

I know ASIHTTPRequest can do it, i'm trying to migrate to AFNetworking, but i have to be sure it will be able to deal with it.

I really searched the internet for this, but i was unable to find this exact answer.

Thank you all.

Yes, AFNetworking does support NTLM authentication (or basically any authentication method) by providing a block-based response to authentication challenges in general.

Here's a code example (assuming operation is a AFHTTPRequestOperation, AFJSONRequestOperation etc.). Before starting the operation set the authentication challenge block like this:

[operation setAuthenticationChallengeBlock:
 ^( NSURLConnection* connection, NSURLAuthenticationChallenge* challenge )
{
   if( [[challenge protectionSpace] authenticationMethod] == NSURLAuthenticationMethodNTLM )
   {
      if( [challenge previousFailureCount] > 0 )
      {
         // Avoid too many failed authentication attempts which could lock out the user
         [[challenge sender] cancelAuthenticationChallenge:challenge];
      }
      else
      {
         [[challenge sender] useCredential:[NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession] forAuthenticationChallenge:challenge];
      }
   }
   else
   {
      // Authenticate in other ways than NTLM if desired or cancel the auth like this:
      [[challenge sender] cancelAuthenticationChallenge:challenge];
   }
}];

Start or enqueue the operation as usual and that should do the trick.

This is basically the method Wayne Hartman describes in his blog applied to AFNetworking.
