A container is an attribute that defines a holder for a piece of identity data. Following is the procedure for adding new attributes to the Liberty Personal Profile Service. The starting point is the Liberty Personal Profile Service configuration screen within the Web Services module.
Enter a name for the container such as CreditCard.
Enter a class name to handle the whole container. This could be used to override the default implementation com.sun.identity.liberty.ws.idpp.plugin.IDPPContainer.
