# Set up Exchange Mapped Security

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

- IDOL server. You must set up IDOL server to process the security information contained in each document. You must also configure user security, 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.
- Exchange Web Service Connector. You must set up the 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 user and group information from Active Directory. For information about how to configure OmniGroupServer, see Retrieve Security Group Information.
- A front-end application for querying IDOL server.
