Recently I started development against CRM 2011. I create simple asp.net website that connects to the CRM 2011 platform using the IOrganizationService Web Service (Using AD authentications). This website allows user to enter basic details of contact for example first name, last name, email address and phone number and create contact in CRM 2011.
I design this website in Visual Studio 2010 using CRM 2011 SDK, which was working fine without any problems. As soon I tried to deploy this website in IIS, I was getting this error message.
The request for security token could not be satisfied because authentication failed.
