# Set up Mapped Security

To use mapped security to protect information that was extracted from a file system by the File System Connector, 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.
- File System Connector. You must set up the File System Connector to include security information (Access Control Lists) in the documents that are indexed into IDOL server. The connector encrypts the ACL and adds it to a document field named `AUTONOMYMETADATA`. 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 group information. Micro Focus recommends retrieving the group information through LDAP. For information about how to configure OmniGroupServer, see Retrieve Security Group Information.
- A front-end application for querying IDOL server.
