User Persistence

Use

For content-sharing interactions between SAP NetWeaver portals in your federation network, users on the consumer portal must also exist in the user store used by the producer portal; otherwise runtime authorization for remote-based content will fail. The reason for this is that remote content is executed on the producer portal using the user profile from the consumer.

A single user store can be implemented in various ways using various hardware or software solutions. Some examples include the following:

• Single user store: Using a single physical user store that serves all your portal installations.

• Distributed user stores with exact duplication: Using two or more distributed user stores, typically one at each portal installation, which are exact replicas of one another.

• Distributed user stores with partial duplication: Using two or more distributed user stores, typically one at each portal installation, where only portal users that are assigned to remote content are copied to the user store on the producer portal.

The federated portal network supports all user stores supported by SAP Enterprise Portal. For more information on the supported user data sources and how to configure them, see UME Data Sources .
