Supersymmetric backgrounds in M-theory often involve four-form flux in addition to pure geometry and, in such cases, the classification of supersymmetric vacua involves the notion of generalized holonomy. Previous investigations of generalized holonomy have focused on the curvature of the generalized connection, but this local information may be incomplete, and higher order integrability conditions of the Killing spinor equation may be essential both to determine the number of supersymmetries preserved by a vacuum and to characterize properly its generalized holonomy.
