  Local supersymmetry enhancement (LSE) is a formalism intended to identify
information needed to describe microstates of supersymmetric black holes that
are realised as brane systems. After illustrating the relationship between LSE
and black-hole microstates with the F1-P system, we review two possible
strategies to apply the LSE mechanism to get microstates of three-charge black
holes. While the former leads to microstates that break the spherical symmetry
of the horizon, microstates built from the latter preserve it, and are numerous
enough to account for (at least) a finite fraction of the M2-M5-P black-hole
entropy.
