This task explains the process of creating a user manually within AX, either as an Active Directory user or as an Active Directory user group.
This task can be performed using PowerShell commands within the Microsoft Dynamics AX 2012 Management Shell. This would not normally be done to create a single user, but as a part of a wider scheme where an organization may script the automation of user accounts from Active Directory. Refer to the Managing users by PowerShell commands section.
To create a user, you will need to log in to AX as a user with appropriate permission (for example as a system administrator) and your Windows user account must have the permission to query the Active Directory.
