The fan-out configuration of the SAP User Management driver provisions one object in the Identity Vault to multiple SAP clients. The SAP User Management Fan-Out driver supports publishing only on the primary connection and not to any additional connections in the fan-out configuration. To support the Publisher channel, the primary connection must be made to a CUA central client.
The SAP User Management Fan-Out driver does fan-out by associations and the destination DN. The policies use entitlements to generate the correct event format for the driver to consume. There are many aspects that make fan-out possible.
