# Mapped Security Architecture

The mapped security architecture includes the following components:

- The Microsoft Dynamics repository
- Dynamics Connector
- Micro Focus OmniGroupServer
- Micro Focus IDOL Content and Micro Focus IDOL Community components
- Micro Focus IDOL Mapped Security plug-in
- A front-end application

Items in Dynamics have associated permissions that specify the users and groups who are permitted, and who are not permitted, to view them. The Dynamics Connector retrieves the items and sends documents to CFS to be indexed into IDOL Server. To each document the connector adds an Access Control List (ACL) which contains the security information. Each time the connector synchronizes with the repository, it updates the ACLs for any documents where the associated permissions have changed.

The IDOL Content component needs the ACL to determine whether a user can view a document that is returned as a result to a query. However, IDOL must also consider the groups that the user belongs to. A user might not be permitted to view a document, but they could be a member of a group that has permission. This means that IDOL requires the user and group information from the Dynamics repository.

The connector can extract user and group information from Dynamics. This functionality is available through the `SynchronizeGroups` action. Based on a schedule, OmniGroupServer sends a request to the connector to run this action and the connector returns the information. OmniGroupServer then stores the user and group information so that the IDOL Community component can query it.

When a user logs on to a front-end application, the application requests the user’s security information and group memberships from Community. Community returns a token containing the information. The front-end application includes this token in all queries the user sends to the Content component.

When a user submits a query, Content sends the result documents and the user’s security token to the Mapped Security plug-in. The Mapped Security plug-in compares the user’s security information and group memberships to each document’s ACL. The plug-in determines which documents the user is permitted to view and returns the results. The IDOL Content component then sends only the documents that the user is permitted to view to the front-end application.
