How the user gets access to EP

The IIS Web server then receives the request for the Enterprise Portal page (see the arrow 2). The Web server verifies whether the user is listed in Microsoft Dynamics AX 2009 and in Windows SharePoint Services or Office SharePoint Server to determine if the user can access the Enterprise Portal site.

• If a user is not listed in both, that user is denied access to the site.
• If the user is listed in both, that user can access the site, and the Web server sends a request to the AOS server to determine which data and content should be displayed (if any).

The AOS server then receives the request for Microsoft Dynamics AX 2009 data (see arrow 3).

• If the user is not listed in any Microsoft Dynamics AX 2009 groups, the user sees an empty Enterprise Portal page in their Web browser.
• If the user is listed in one or more groups, the Enterprise Portal page displays content and data defined by the user group permissions.

The Enterprise Portal security components in an extranet deployment can include one or more firewall devices and multiple domain controllers, but the process of determining page access and the content shown on pages is the same.
