Authenticate users with Microsoft Dynamics CRM 2013 web services

Applies To: Dynamics CRM 2013

Microsoft Dynamics CRM supports two security models for authentication: claims-based authentication and Active Directory authentication. The type of authentication used depends on the type of deployment your application is accessing: Microsoft Dynamics CRM Online orMicrosoft Dynamics CRM 2013.

In addition to using the correct security model, applications must establish a communication channel with the Microsoft Dynamics CRM web services on the target deployment. The Microsoft Dynamics CRM SDK run-time assemblies use Windows Communication Foundation (WCF) technology to establish this communication channel.

The Microsoft Dynamics CRM SDK simplifies use of WCF technology and claims-based authentication by providing helper proxy classes that make it easy to write applications that connect to and authenticate with the Microsoft Dynamics CRM web services. By using these helper classes in your application, you can access any Microsoft Dynamics CRM deployment using the same code and you don’t have to become an expert in claims-based security or WCF programming.
