Helper code: SystemUserProvider class

 

Applies To: Dynamics CRM 2013

Download the Microsoft Dynamics CRM SDK package. This sample can be found in the following location in the download package:

SDK\SampleCode\CS\HelperCode\SystemUserProvider.cs

SDK\SampleCode\VB\HelperCode\SystemUserProvider.vb

Requirements

The logged on system user must have system administration privileges for this sample code to create the new user accounts. For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.

Demonstrates

The SystemUserProvider class demonstrates how to programmatically create additional users in Active Directory andMicrosoft Dynamics CRM 2013.

Several SDK samples require additional (fictitious) system users to exist in Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online, other than the logged on user, for the sample to perform its intended task. These samples use the SystemUserProvider class methods to create these additional required users. Since it currently is not possible to programmatically create a new Microsoft account user, when running against a Microsoft Dynamics CRM Online server, the code just prints the required user information to the console. You can then manually add and invite those users if desired.
