/**
 * An extension of the {@link StubPersonAttributeDao} that is able to identify itself
 * by populating the backing map with the received username. This allows for static attributes
 * to be merged with other DAOs via {@link org.jasig.services.persondir.support.MergingPersonAttributeDaoImpl}.
 * Without the unique identifier that is username, the merge would fail resulting in two distinct attribute sets
 * for the same principal in the ultimate attribute map.
