Authentication and Authorization

Microsoft Dynamics AX uses integrated Windows authentication to authenticate
Active Directory users. If you configure Microsoft Dynamics AX to use a
different authentication provider, users are authenticated by that provider.
Authorization of access to data, business functionality, and presentation elements
(forms, menus, fields and reports) is governed by Microsoft Dynamics AX
security. Anonymous web users can access the Enterprise Portal with limited
functionality.

A client provides an interface to Microsoft Dynamics AX data and functionality.
An external application integrates with Microsoft Dynamics AX to
programmatically integrate functionality or exchange data. Some features
include:

• The Microsoft Dynamics AX Windows client is a native 32-bit program that provides a rich user interface.

• Supported web browsers give access to Microsoft Dynamics AX functionality and data through the Enterprise Portal.

• External applications interact with Microsoft Dynamics AX through the use of services and the Application Integration Framework (AIF). Services and AIF provide an extensible framework for XML-based enterprise application integration (EAI), business-to-business (B2B), and service-oriented architecture (SOA) scenarios.

NOTE: Use services and AIF to interact with the Microsoft Dynamics AX application. Do not use the .NET Business Connector to integrate with the Microsoft Dynamics AX application.The application tier consists of one or more of the following Microsoft Dynamics AX components or computer roles.
