Authentication Required Error SharePoint 2010
I am trying to generate a proxy class for my Lists in SharePoint using the odatagen OData Client for Objective C.
On my mac at a terminal I am running the following command:
./odatagen /uri=http://mydomain/_vti_bin/listdata.svc /out=/myoutpath /auth=windows /u=DOMAIN/username /p=password
The above command continually returns an Authentication failed error as below:

I can authenticate successfully when I visit the listdata.svc URL in a browser. Authentication is set to NTLM but I have tried Kerberos for the web application also.
As I understand it the odatagen command should use the supplied credentials to authenticate to SharePoint.
Has anybody tested this proxy class generation using odatagen with SharePoint listdata.svc?
