  We investigate the expectations for the light Higgs signal in the MSSM in
different search channels at the LHC. After taking into account dark matter and
flavor constraints in the MSSM with eleven free parameters, we show that the
light Higgs signal in the $gamma\gamma$ channel is expected to be at most at
the level of the SM Higgs, while the $h\rightarrow b\bar{b}$ from W fusion
and/or the $h \rightarrow\tau\bar\tau$ can be enhanced. For the main discovery
mode, we show that a strong suppression of the signal occurs in two different
cases: low $M_A$ or large invisible width. A more modest suppression is
associated with the effect of light supersymmetric particles. Looking for such
modification of the Higgs properties and searching for supersymmetric partners
and pseudoscalar Higgs offer two complementary probes of supersymmetry.
