MIM service and portal
The MIM service provides all the necessary capabilities for policies and workflows. All objects like groups, users, workflows, requests, and other resources used in MIM are stored as objects in the MIM Service database. These objects can be modified with typical CRUD (Create, Read, Update, Delete) operations requests to the MIM service Identity-Management (IdM) Platform.
With the MIM portal, users interact with the system by using a web browser. The usage depends on the permissions; users can be granted to do requests, respond to approval requests, cancel existing pending requests, or manage objects in the IdM system:
The default MIM Portal is based on a SharePoint solution and can be highly customized. You can find some example configurations at https://docs.microsoft.com/en-us/microsoft-identity-manager/reference/mim-portal-customizations.
