# Set up SharePoint Mapped Security

To use mapped security to protect information that was extracted from a SharePoint repository, set up the following components:

- IDOL Server. You must set up the IDOL Content component to identify the security type associated with each document. You must also configure the IDOL Community component, so that IDOL sends user and group information to the front-end application when a user logs on. For information about how to set up IDOL Server, refer to the IDOL Document Security Administration Guide.
- SharePoint Remote Connector. You must set up the SharePoint Remote Connector to include security information (Access Control Lists) in the documents that are indexed into IDOL server. You must also add a field to each document that identifies the security type. For information about how to do this, see Retrieve and Index Access Control Lists.
- OmniGroupServer. You must set up OmniGroupServer to retrieve, and then combine, group information from SharePoint and either Active Directory or a claims provider. This results in three repositories in OmniGroupServer, but only the repository that contains the combined information should be queried by IDOL Community to populate user security info strings. OmniGroupServer retrieves SharePoint groups by sending the `SynchronizeGroups` action to the SharePoint connector. OmniGroupServer extracts NT security information directly from Active Directory. For information about how to configure OmniGroupServer, see Retrieve Security Group Information using OmniGroupServer.
- A front-end application for querying IDOL Server.
